Light’s Posthumous Letter by Norazha Paiman

We only see stars
that died millennia past—
the sky is a tomb.

by Norazha Paiman

Due to the finite speed of light (299,792,458 meters per second) and the vast distances in space, we observe celestial objects not as they are now, but as they were when their light began its journey to Earth.

A light-year is the distance light travels in one year (approximately 9.46 trillion kilometers). This temporal delay means that astronomy is fundamentally the study of the past; every observation is historical documentation, and the present state of the universe remains forever invisible to us. The night sky is effectively an archive of extinct or transformed objects whose light continues to travel long after the original source has changed or ceased to exist.

Freckles by John Hawkhead

black hole horizon
the galaxy of freckles
mum used to own

by John Hawkhead

A black hole horizon, or event horizon, is a boundary around a black hole beyond which neither matter nor light can escape the black hole’s gravitational force. Any object that crosses the horizon is pulled irrevocably into the black hole and cannot return. It is currently thought that each of the estimated 200 billion large galaxies in the observable universe have a black hole at their centre – although some smaller galaxies do not. Black Holes grow by accreting stars, dust and gas that come too close to the horizon.

Although some human cultures believe in the concept of reincarnation, death is mostly considered to be a ‘point of no return’ regardless of any belief in an afterlife. This poem remembers the death of the poet’s mother and the freckles she had as a child.

Yearning by Quinn Clark

Galactic arms curl
Into tight spirals for warmth—
Sometimes, so do we.

by Quinn Clark

‘Yearning’ is inspired by the hot gas and plasma present between galaxies and within galactic clusters, as well as a sentimental connection to human thermoregulation. Although this hot intracluster gas ought to cool off, observations show a contradictory reduced cooling rate. Some astronomers theorise that this prolonged heat and turbulence could be due to interactions with matter flowing from supermassive black holes.

This poem first appeared in The Best Haiku Anthology 2024 published by Haiku Crush.

All-Seeing by Scott Edgar

Galaxies can run
But can’t hide – Gravity’s lens
Will bring them to light

by Scott Edgar

This haiku explores the phenomenon of gravitational lensing, where the gravity of a massive object bends light from more distant galaxies behind it. This effect allows astronomers to detect and study galaxies that would otherwise remain hidden — brought into view by gravity itself.

Message Lost by Scott Edgar

Through interstellar
Space to us then getting lost
In yellow street lamps

by Scott Edgar

This haiku captures the bittersweet journey of starlight. After traveling tens or hundreds or even billions of light years through interstellar space, it ends up lost in the ambient glow of artificial light.

On a practical level, it reflects the impact of light pollution: how the soft yellow of street lamps drowns out the ancient light of stars, severing a connection that once bound us to the night sky. What was once a shared human experience of looking up and seeing the cosmos is now dimmed, both literally and spiritually.

the lion’s gate by Mariya Gusev

roar of tiny suns
they call them dandelions
for a good reason

by Mariya Gusev

This poem was inspired by research that allows us to ‘see’ inside the sun by listening to the dynamic movement of the sun. It was also inspired by the song ‘Why Does the Sun Shine? (The Sun Is a Mass of Incandescent Gas)’ by They Might be Giants:

The sun is mass of incandescent gas, a gigantic nuclear furnace.
Where hydrogen is built into helium at a temperature of millions of degrees.
Yo ho it’s hot, the sun is not a place where we could live.
But here on earth there’d be no life without the light it gives.
We need its light, we need its heat, we need its energy.
Without the sun, without a doubt, there’d be no you and me.

The sun is far away, about 93,000,000 miles away, and that’s why it looks so small.
And even when it’s out of sight, the sun shines night and day.

This Battle is Inborn by Maryam Imogen Ghouth

The sun holds a war—
inward pull and outward fire—
I am made of her.

by Maryam Imogen Ghouth

This haiku reflects the Sun’s internal tension—a delicate equilibrium between the inward pull of gravity and the outward force of nuclear fusion. It is this ongoing balance that keeps the Sun stable and radiant. In a world that often demands binary choices—light or dark, order or chaos—this cosmic tension reminds us that life itself depends on the coexistence of opposing forces and that we, like the Sun, are shaped by contradiction.

eons by Mariya Gusev

path of a comet
orbit eccentricity
classified as love

by Mariya Gusev

Orbital eccentricity is a measure of how much a celestial body’s orbit deviates from a perfect circle. The more “stretched” or flattened an orbit is, the higher the eccentricity, which ranges from 0 to 1, where 0 represents a circular orbit and 1 represents a parabolic orbit (which is not a closed orbit). Eccentricity values between 0 and 1 indicate elliptical orbits, with higher values indicating more elongated ellipses.

Comets often have highly elliptical or near-parabolic orbits because they originate from the Oort Cloud or Kuiper Belt, extremely distant regions of the solar system. When these objects fall towards the Sun, their orbits are strongly influenced by the Sun’s gravity, resulting in elongated paths. Interactions with planets, especially Jupiter, can also alter a comet’s orbital eccentricity.

Short-period comets (those with orbital periods less than 200 years) tend to have lower eccentricities than long-period comets, which can take thousands or even millions of years to orbit the Sun.

The sciku above explores the sometimes complex paths of human relationships.

magic cloak by Susan Polizzotto

stillness of the stars
traveling through space and time

by Susan Polizzotto

This poem uses the season word “light jacket” to allude to nuclear fusion in a playful way. Light emitted by a star is like a magic cloak that enables it to travel through space and time. Just as a person’s jacket reveals something of their personality, a star’s jacket provides information about its location, movement, and other characteristics and properties.

The Big Decay Theory by Martina Matijević

our universe weds
the Hawking radiation
final cul-de-sac

by Martina Matijević

Researchers from Radboud University now believe the universe will decay faster than previously thought, due to Hawking radiation. White dwarfs and black holes will evaporate in about 10⁷⁸ years, much sooner than the older estimate of 10¹¹⁰⁰ years. Surprisingly, black holes and neutron stars will disappear around the same time.

The vast universe by Martina Matijević

the vast universe
divorced the Hubble constant
citing lack of space

by Martina Matijević

A recent study confirms that the universe is expanding faster than theoretical models predict, adding more evidence to the ongoing “Hubble tension” crisis.

Researchers measured the Hubble constant using a highly precise distance measurement to the Coma Cluster, revealing a local expansion rate of 76.5 kilometers per second per megaparsec. This new data challenges current cosmological models and suggests that adjustments to our understanding of the universe’s growth may be necessary.

Cassiopeia A by Scott Edgar

Fusion bestowed life
‘Til your iron heart wrought death
Your ghost is ablaze

by Scott Edgar

This haiku represents the life cycle of a star from its birth through fusion to its death when fusion no longer offsets the pull of its core that’s turned to iron over its life and finally the supernova, its remnant, that results from the star’s instant collapse (if the star was big enough).

This haiku was inspired by this image that I saw of the Cassiopeia A supernova remnant:

Trigonometry by John Hawkhead

trigonometry
measuring a new distance
between our stars

by John Hawkhead

Trigonometry is a branch of mathematics concerned with the functions of angles and their application to calculations. Trigonometric functions are used to find unknown angles and distances from known or measured angles in geometric figures.

For example, astronomers apply trigonometry to calculate how far stars and planets are from Earth. Similarly, astronauts calculate the speed they are moving in a spacecraft by using the distance from a known location to calculate an unknown distance to another location.

Humans also use the stars to reference predestined future events such as in Shakespeare’s ‘star-crossed lovers’ (where Romeo and Juliet’s romantic relationship is doomed).  Potential lovers may look to the stars to predict how distances between one person and another can be bridged, or how to predict who one is fated to be with.

How To Navigate Our Universe by Mary Soon Lee – Book Review

It’s safe to say that I’m a fan of poet and author Mary Soon Lee. I adored Elemental Haiku, her series of haiku based on each element of the period table. I also really enjoyed The Sign of the Dragon, a stunning epic fantasy poem sequence that’s well worth seeking out (and has recently been published in an illustrated version). And my three-part interview with her was fascinating, leading to a continuing and delightful sporadic correspondence over the past few years.

So, please take this review of her 2023 collection of poetry How To Navigate Our Universe with a pinch of salt. To add further seasoning, Mary herself arranged for a copy of her book to be sent to me, although not with any request for coverage on The Sciku Project. On finishing reading it, however, I decided I wanted to cover it anyway.

Salted or not, How To Navigate Our Universe is a joy.

Mary first mentioned the project to me in the third part of our interview, way back in 2019. Followers of her work (and those signed up to her newsletter) will have seen poems in the series trickling into the wild ever since.

Split over five parts, the collection comprises of 128 poems, the overwhelming majority of which are part of a ‘How To’ sequence, originally started from a prompt in The Daily Poet by Kelli Russell Anodon and Martha Silano. The titles in the sequence are wonderful, ranging from ‘How to Mislay Constellations’ to ‘How to Tease Jupiter’ (my personal favourite).

Throughout, Mary’s poetic skills are on full display. For the most part these are brief affairs. Whilst there aren’t many haiku (more haiku please!) most are less than 30 lines long, and those lines are generally 5 words or less. What I’m trying to convey with this overly quantitative approach to poem length is that Mary manages to do a lot with remarkably little.

Of course, this should come as no surprise to fans of Elemental Haiku. In my review of that collection I said “Mary Soon Lee walks the balance between information and artistry perfectly. Her poems are graceful, humorous and fascinating, sometimes all three in a single haiku.”

Copy-and-paste.

Writing haiku teaches us many things, some more useful than others. Being able to say a lot with a little is the most valuable of them all. Being able to do so elegantly and include information, emotion, humour, narrative… well that’s the sign of a master of their craft.

So sure, there aren’t many haiku in the book, but the poems in How to Navigate Our Universe use the same poetic brevity that Mary demonstrated in Elemental Haiku. Indeed, some of these poems come across as chains of haiku, even though they aren’t.

Gravitationally collapse a nebula.
Fuse hydrogen into helium.
If desired, explode.

– How to be a Star

There are some wonderful turns of phrase. ‘How to Mislay Constellations’ starts with the couplet ‘Set them down carefully, // each star in its place,’. There’s nothing fancy about the lines but its precise sparseness conveys so much of the poem to come. Many of the poems are sequences of two-line stanzas like ‘How to Mislay Constellations’. It’s a form that compliments Mary’s style I think.

Breaking the couplet poems Mary shows she can handle other forms just as well. One of my favourite poems is dedicated to the memory of Cecilia Payne-Gaposchkin, the British-American astronomer who in 1925 proposed that stars were composed primarily of hydrogen and helium. The poem, ‘How to Heed Hydrogen’, is a pantoum and it’s stunning, weaving its repeating lines around on themselves to celebrate a pioneering astronomer, her most famous achievement and the barriers and challenges faced by a female scientist.

‘How to Heed Hydrogen’ appears in Part IV which is titled ‘Pioneers’. Other famous (and not so famous) names receive poems alongside Payne-Gaposchkin, including Stephen Hawkins, Henrietta Swan Leavitt, Galileo Galilei and Valentina Tereshkova (another lovely poem that balances achievement and feminism without taking anything away from Tereshkova herself).

Groundless, that first step
beneath the unblinking stars,
historic space walk.

– In memory of Alexei Leonov
[May 30, 1934 – October 11, 2019]

Only in the final, shortest part of the collection, Part V: Space Dust, does Soon Lee depart from the ‘How to’ formula. It’s a little jarring and makes the poems contained within feel like an afterthought. They aren’t and I can see why they’ve been included in this collection, but it’s a shame that they break from the cohesion of the previous 100+ poems.

As a collection, How to Navigate Our Universe is an overflowing trove of wonderful poems that intrigue and stimulate curiosity. There aren’t any notes to explain anything referenced in the poems but many times I’ve turned to the internet to discover more about something mentioned in a poem. You can feel Mary’s interest in the stars baked into the spine of this book, her fascination with space and the women and men who dream beyond our planet. The delightfully dreamy front cover helps too, the art by Mary’s own daughter Lucy Lee-Moore.

I might be biased but I can comfortably say that How to Navigate Our Universe is the best science-related poetry collection I’ve read in several years.  It’s a remarkable achievement. Stellar even.

Space time by John Hawkhead

space-time it appears we both needed it

by John Hawkhead

Under the rules of special relativity, time is not separated from the three dimensions of space. This is because the observed rate at which time passes for an object depends on the object’s velocity relative to its observer. Gravitational fields can slow the passage of time for an object as seen by observers outside the field.

In space, the position of an object is specified by three co-ordinates called xy and z. A point in spacetime is called an event, which is a three-dimensional location in space plus the position in time (the fourth dimension). Therefore, an event in space-time has four coordinates xyz and t.

Partners in life may sometimes need space and time apart to consider where they are or where they are going in a relationship. Hopefully, the sciku gives a double insight into these thoughts and a juxtaposition between them.

Redshift was the key.

science persevere by Allison Lamoureux

rocket explodes bright
science fails but we do not
science persevere

by Allison Lamoureux

This sciku was inspired by the perseverance of science and technology, in this case the aerospace industry. When a rocket explodes, space companies and organizations investigate what went wrong in order to do better next time. This perseverance of the human spirit and drive to continue to innovate is inspiring, and can be seen across science disciplines.

In fact, the Mars rover ‘Perseverance’ was specifically named by school student Alexander Mather for humanity’s perseverance, saying “We are a species of explorers, and we will meet many setbacks on the way to Mars. However, we can persevere. We, not as a nation but as humans, will not give up. The human race will always persevere into the future”.

The deepest shade by Mike Fainzilber

the deepest shade of cold
an ambush
for the light

by Mike Fainzilber

The James Webb Space Telescope takes images of the furthest (hence oldest) and faintest objects in the universe using infrared light. In order to do this without being blinded by infrared radiation from heat emitters (including its’ own components) it has detectors that must be hyper-cooled to temperatures of less than 7 degrees Kelvins (which is approximately -266 C or -447 F).

by John Hawkhead

A protostar is a young star still gathering mass from its parent molecular cloud. The protostellar phase is the earliest the process of stellar evolution.

A sonogram is a picture made by ultrasound waves to show the inside of the human body, including in pregnancy assessment.

Hibernation by Joy Stahl

Survival in space
Cold sleep on long missions
Arctic Ground Squirrel

by Joy Stahl

I’m a huge fan of science fiction novels and shows that use hibernation chambers to allow humans to reach distant planets in their lifetime.

I read an article about scientists who are studying arctic squirrels and how they hibernate, to create hibernation solutions for astronauts. Arctic squirrels are super-hibernators . They hibernate over winter for 7 to 9 months, reducing their core body temperature from 37 °C (99 °F) to as low as −2.9 °C (26.8 °F), and yet they manage to retain muscle and bone mass during this extended hibernation. Understanding this remarkable adaptation may help researchers looking at prolonged space travel and may also lead to improved critical and emergency health care and treatments.

Sun Trails by Joshua St. Claire

magnetic lines of force
radiating from the sun
contrails

by Joshua St. Claire

The movement of the charged particles of the sun’s plasma creates a powerful and complex magnetic field. The origin and evolution of the field is still an active area of research, but it’s proven to have an impact on the Earth. The periodicity of the intensity of the sun’s magnetic field has a demonstrable impact to the climate of Earth and solar flares pose a risk to electronics, as demonstrated by the Carrington Event of 1859.

Recently, stories circulated in the media saying that “a piece of the sun has broken off.” While these headlines were sensational, these observations underscore the fact that much of what happens in the sun and, by extension, other stars remains a mystery.

Planetarium by John Hawkhead

planetarium
she reaches across space
to find my hand

by John Hawkhead

In the 2008 USA presidential election, Senator John McCain criticised the value (and cost) of planetariums, as being little more than “overhead projectors”.

Yet planetariums, as well as being a unique form of entertainment, are valuable science communication tools: interactive and immersive pedagogic instruments for astronomical education.

For example, research by Plummer (2008) suggests that attending a planetarium program increased understanding of celestial motion in students aged 6 to 8 years old. Planetariums are also especially valuable for those living in large towns and cities, where light-pollution prevents most stars from being visible.

To celebrate the value and power of planetariums, the second Sunday of every March is International Day of Planetariums.

Suspended by Michele Rule

Metal formation
Buried deep inside the moon
Suspended mass

by Michele Rule

When I read about the discovery of a huge metal mass buried deep underground below the surface of the moon, I immediately jumped to the idea of a spaceship crash site. But reading more I learned about several possible causes, one being an asteroid crash and the other related to the magma solidification of the Moon’s surface. Both involved the suspension of a metal “structure” in a large mass, five times the size of the big island of Hawai’i.

Young Star by petro c. k.

young star
accretion of dust
on a photo

By petro c. k.

When a star is just beginning to form, it collects a cloud of dust and particles that exist around it called a protoplanetary disk. It is thought the protoplanetary disk is connected to the star by a magnetic field, and the particles follow the field until they crash onto the surface of the growing star.

Studying and observing the phenomena of such dust in other stars gives new insights into how our own star, the sun – and our subsequent solar system – formed.
