Still working on some things here and there, but Iβll be (temporarily) opening commissions for the time being. Thereβs unlimited slots at the moment, but I may close during midterms to focus on my studies. Any other questions, donβt hesitate to DM me on here or on Discord.
If you canβt support financially, then feel free to reblog! ^^
Weβre excited to announce that weβve selected five new surveys for the soon-to-launch Nancy Grace Roman Space Telescope! These observations will unveil myriad worlds, provide dazzling looks at globular clusters and two nearby galaxies, and examine the early universe in unprecedented detail. Hereβs a preview of each new survey.
This ground-based image of the Andromeda Galaxy highlights the large field of view of NASA's soon-to-launch Nancy Grace Roman Space Telescope, with Hubble's field of view and a full moon shown for comparison.
Mapping Andromeda & Triangulum
One Roman survey will take spying on the neighbors to the extreme, creating the most detailed mosaics ever of two of the closest big galaxies to the Milky Way: Andromeda and Triangulum. Roman will observe each galaxy repeatedly, ultimately mapping more than half a billion stars in 3D and monitoring how they move and change over time.
That will help astronomers reconstruct how the galaxies formed and evolved, including how theyβve interacted with each other over the course of billions of years. Astronomers will better understand how stars are born, live, and die in galaxies beyond our own.
The survey will also probe each galaxyβs dark matter underpinnings. This mysterious material doesnβt emit light or interact with normal matter except gravitationally, yet it accounts for the vast majority of the universeβs mass. Watching how gravity guides the movement of stars in these galaxies will help astronomers trace the distribution of both normal and dark matter in exquisite detail.
NASA's Kepler space telescope, shown in this artist's concept, revealed that there are more planets than stars in the Milky Way galaxy. NASA's Nancy Grace Roman Space Telescope will extend Kepler's legacy by covering the same area in even sharper detail, which is sure to unearth many more planets and other objects.
Kepler Revisited
As NASA's first dedicated planet-hunting mission, the Kepler space telescope searched a slice of our galaxy for Earth-sized planets. Now, Roman is set to retrace Kepler's footsteps, covering the same area in even sharper detail.
The Roman-Kepler Legacy Survey will capture detailed images of all 200,000 objects Kepler observed, including over 4,000 stars that may host planets. And Romanβs more powerful view will reveal things Kepler was unable to see, adding up to about 17 million stars and brown dwarfs β in-between objects that are too heavy to be classified as planets, but not quite massive enough to become stars.
The survey will also probe Tatooine-like worlds that orbit pairs of stars. These stellar couples are so close that they easily blur together, which is why we need a crisp view like Romanβs to tell them apart.
This image from NASA's Hubble Space Telescope captures what looks like a galactic glitter bomb in the night sky. Called 47 Tucanae, this stellar collection is one of about 150 globular star clusters in our Milky Way galaxy. While previous telescopes have only observed small pieces of it at a time, Roman will capture it in its entirety in a single snapshot. In about one week of observation time, NASAβs Nancy Grace Roman Space Telescope will survey this cluster and three others covering a total area that would take NASAβs Hubble Space Telescope around 18 years to cover, while matching its resolution.
Globular Cluster Survey
Romanβs globular cluster survey will take the most complete inventory ever of stars in four relatively nearby groups of ancient, densely packed stars: M4, NGC 6397, 47 Tucanae, and Omega Centauri.Β
In just one week of observation time, Roman will survey a total area that would take NASAβs Hubble Space Telescope around 18 years to cover, while matching its resolution. That will help astronomers tally up and map their hundreds of thousands of stars while identifying very faint objects, like brown dwarfs.
This is a Hubble Space Telescope view of a portion of GOODS-South, the southern field of a large deep-sky study by several observatories to trace the formation and evolution of galaxies. The image shows a rich tapestry of 7,500 galaxies stretching back through most of the universe's history. The farthest galaxies, a few of the very faint red specks, are seen as they appeared more than 13 billion years ago, or roughly 650 million years after the big bang.
Baby Galaxies
The GRACE (Grism Reionization and Cosmic Evolution) Survey will spend about 2.5 weeks peering far into the universeβs past to hunt for some of the earliest galaxies. Its main goal is to shed light on how the cosmos transitioned from being filled with an opaque gas to becoming crystal clear, allowing light to travel across the universe.
This is the era when the first galaxies began lighting up the cosmos. The GRACE survey aims to find ten times more of the earliest known galaxies than all other telescopes have discovered to date. Scientists will be able to see how galaxies, stars, black holes, and the cosmic web evolved from the dawn of the universe to the present day.
The eXtreme Deep Field, or XDF, was assembled by combining 10 years of NASA Hubble Space Telescope photographs taken of a patch of sky at the center of the original Hubble Ultra Deep Field. NASAβs Nancy Grace Roman Space Telescope will conduct a similar observation covering a patch of sky more than 140 times larger.
Extreme Deep FieldΒ
The RXDF (Roman eXtreme Deep Field) will stare deep into a small patch of sky, essentially collecting a cosmic core sample. This mega-exposure will be similar to but more than 140 times larger than Hubbleβs eXtreme Deep Field.Β
And instead of taking a single snapshot, Roman will repeat the observations over time. Stitching together a detailed time-lapse of a relatively large chunk of the early universe will help astronomers track how the earliest galaxies, black holes, and other structures formed and changed across cosmic history. The observations could also catch some of the first supernova explosions and show how they shaped the early cosmos.
NASAβs Nancy Grace Roman Space Telescopeβs three main observing programs, highlighted in this infographic, will enable astronomers to view the universe as never before, revealing billions of cosmic objects strewn across enormous swaths of space-time.
All of this is in addition to Romanβs three core surveys and first announced bonus survey, which will transform our view of the universe. Follow along with Romanβs road to launch at nasa.gov/roman, and virtually tour the Roman observatoryΒ here.

happy nine year anniversary to 17776 btw. i can't imagine what it mustve been like clicking on an sbnation article back then and finding the story of a lifetime hidden inside. A wild ride and a story that will stick with me for eternity, no doubt.

Send your name to fly on Roman and download a boarding pass like this one with your name on it!
Whatβs the farthest youβve ever traveled from home? Want to beat your record by about a million miles? Submit to have your name added to a memory card that will be attached to a plaque on our Nancy Grace Roman Space Telescope traveling a million miles away!
Prior to Romanβs launch, an SD card loaded with submitted names will be attached to this plaque where the square outline is.
After launch on August 30, Roman will journey way out to the second Sun-Earth Lagrange point (L2), the same orbit as our James Webb Space Telescope. At L2, the gravity of the Sun and Earth, together with an objectβs motion around the Sun, let it stay lined up with Earth as they orbit. That will give Roman a relatively steady orbit without using much fuel. Like Webb, Roman will trace out a large orbit around the actual L2 point β much larger than the Moonβs orbit around Earth β and the two will easily be kept far apart.
Telescopes at L2 also have a constant, unobstructed view of a wide swath of the sky. Earth won't block much of Roman's view since it will be so distant! And at L2, heat from Earth, the Sun, and the Moon have less effect on infrared telescopes, which βseeβ heat.
The Roman Telescope model has its boarding pass! Do you have yours?
Send your name here. Submissions close July 16. Follow along with Romanβs road to launch at science.nasa.gov/blogs/roman!
