This illustration shows the relative scale of the Nancy Grace Roman Space Telescope and a Tyrannosaurus rex. Roman is over 42 feet (12.7 meters) long ā about the length of a T. rex ā and over 14 feet (4.4 meters) wide when fully deployed. Roman also weighs around 18,000 pounds, or 8,000 kilograms (dry mass), which is the approximate mass of a T. rex as well.
Did you know NASAās Nancy Grace Roman Space Telescope is both roughly as long and as massive as a Tyrannosaurus rex? This observatory, which will move to the launch site at NASAās Kennedy Space Center in Florida very soon, is over 42 feet (12.7 meters) long and weighs around 18,000 pounds (8,000 kilograms), not including the fuel. Letās explore some of the components that bring Roman to T. rex proportions.
Artist's concepts of NASA's Nancy Grace Roman Space Telescope (left) and NASA's Hubble Space Telescope (right), highlighting the 7.9-foot (2.4-meter) primary mirrors that sit in the heart of each observatory.
At the observatoryās heart sits a mirror thatās 7.9 feet (2.4 meters) across and 410 pounds (186 kilograms), or about the length and weight of a protoceratops! Romanās primary mirror is the same size as the Hubble Space Telescopeās main mirror, but less than one-fourth the weight thanks to major improvements in technology.
Technicians installed Romanās primary instrument, the Wide Field Instrument (pictured at left), in the fall of 2025.
The missionās 300-megapixel infrared camera, called the Wide Field Instrument, is over 8 feet (about 2.5 meters) tall, which is about the length of a triceratops skull. It will give Roman the same angular resolution as Hubble while capturing an area of sky at least 100 times larger. The mission will gather data up to 1,000 times faster than Hubble.
Its sweeping cosmic surveys will help scientists discover new information about planets beyond our solar system, untangle mysteries like dark energy, and map how both normal matter and dark matter are structured and distributed throughout the universe. Casting such a wide, deep ānetā into space will give astronomers plenty of cosmic bycatch as well; Romanās crisp, panoramic views will offer practically limitless opportunities for astronomers to do all kinds of exciting science.
The Coronagraph Instrument was installed on Romanās instrument carrier in October 2024.
Romanās Coronagraph Instrument is about as wide (5.5 feet, or 1.7 meters) as a velociraptor is long. The Coronagraph is designed to demonstrate new technologies for directly imaging planets around other stars. It will block the glare from a star and make it possible for scientists to see the faint reflected light from planets in orbit around them.
The Coronagraph aims to photograph worlds and dusty disks around nearby stars in visible light to help us see giant worlds that are older, colder, and in closer orbits than the hot, young super-Jupiters direct imaging has mainly revealed so far.
This photo shows Romanās 18 detectors, which are the heart of the missionās 300-megapixel camera.
Romanās āeyes,ā 18 saltine cracker-sized detectors in its primary instrument, are each about as tall as an allosaurus tooth. They each have about 16.8 million tiny pixels for a total of 300 million, which means Romanās images will be super hi-res. Each detector is made of millions of mercury-cadmium-telluride photodiodes (sensors that convert light into an electrical current), one for each pixel.
Principal technician Billy Keim installs a cover plate over Romanās detectors.
The detectors are secured to a silicon electronics board that will help process the light signals using indium, a soft metal that has roughly the same consistency as chewing gum. Together, these ultra-sensitive detectors can capture vast areas of sky in a single shot while still revealing incredibly fine detail, allowing Roman to map the cosmos faster and more precisely than ever before.
Romanās electrical wiring was installed on the spacecraft flight structure in the summer of 2023.
There are 1,000 pounds, or 450 kilograms, (the weight of a pachycephalosaurus) of electrical cabling, made up of about 32,000 wires and 900 connectors, laced throughout the observatory. If the wires were laid out end-to-end they would span 45 miles ā nearly enough to trace the entire perimeter fence in the imagined Jurassic Park! Functioning as the Romanās ānervous system,ā the cabling enables different parts of the observatory to communicate with one another, provides power, and helps the central computer monitor the observatoryās function.
The Roman observatory was fully integrated on Nov. 25, 2025, at NASAās Goddard Space Flight Center in Greenbelt, Md.
Romanās six solar panels each measure about 7 by 10 feet (2 by 3 meters), collectively giving Roman a āwingspanā similar to a pteranodonās! Together, they will provide a total of 4 kilowatts of power, which is about the same rate that a modest rooftop solar panel system produces during the daytime.
Over the course of two days in June 2025, eight technicians installed Romanās solar panels onto the outer portion of the observatory.
The panels are covered in a total of 3,902 solar cells that will convert sunlight directly into electricity much like plants convert sunlight to chemical energy. When tiny bits of light, called photons, strike the cells, some of their energy transfers to electrons within the material. This jolt excites the electrons, which start moving more or jump to higher energy levels. In a solar cell, excited electrons create electricity by breaking free and moving through a circuit, sort of like water flowing through a pipe. The panels are designed to channel that energy to power the observatory.
Romanās high-gain antenna will provide the primary communication link between the spacecraft and the ground.
The radio dish that will send data across a million miles of intervening space back to Earth spans 5.6 feet (1.7 meters) in diameter. Thatās about the size of the largest known dinosaur footprints, yet it weighs only 24 pounds (10.9 kilograms). Its large size will help Roman send radio signals across a million miles of intervening space to Earth. The dual-band antenna will use one frequency band to receive commands and send back information about the spacecraftās health and location. It will use another frequency band to transmit a deluge of data at up to 500 megabits per second.
Weāre only a few months out from launch, and so close to a completely new understanding of the universe and our place within it. Follow along with Romanās road to launch at nasa.gov/roman, and virtually tour the Roman observatory here.

my unpopular opinion is that i hate tiktok because now people just publicly watch loud ass videos in public spaces with no regard for anyone else. 100% it was not this bad with youtube, itās such a different thing with tiktok. put on headphones. you are grown.
This is it! This is what social media/smart tech have done! Theyāve rotted away any distinction between private and public.
Yes, we do have the right to make demands on public behavior. Of course we do. Have you never heard of laws and etiquette? Iām not allowed to grocery shop naked. You canāt rummage through my purse. I canāt have a work meeting in the middle of a movie theatre.
I remember when it was taboo simply to answer your cell phone in public. The person answering would apologize and try to go to a more private area. Then public calls were normalized. Then putting people on speaker. Then listening to music without headphones. Do you know how many times I have hiked up a mountain or driven to the beach, only to be met with someone blaring shitty top 40 music from their portable speaker, because Heaven forbid you go one hour without noise?
Old woman yells at cloud and all that, but I canāt believe someone is not only admitting this behavior, but saying itās a good thing! No one likes you! Youāre a menace!
For those who don't know: Ikumi Nakamura is the woman who was senior artist on Bayonetta, and designed the titular character along with Hideki Kamiya. Their greatest moment of bonding was over their insistence that Bayonetta keep her glasses on at all times.
Nakamura cannot go to horny jail. She is the warden.
wait, you mean that by spending decades joking about how schools are disease vectors because children are just naturally disgusting, adults were ignoring a structural problem they had created? how surprising and not at all precedented
Finding out that the author behind A Series of Unfortunate Events is a Jew makes the sheer absurdity of the incompetence of the adults in the Baudelairesā lives make soooo much more sense when you start seeing Count Olaf as a metaphor for antisemitism. How they repeatedly tell whoever their current guardian is who and what is after them and they just patronizingly tell them that they donāt know what theyāre talking about or choose not to see through the very obviously thin disguise (a metaphor for dog whistles). The gaslighting. The willful ignorance. Itās so painfully familiar.
The Netflix adaptation makes this even more painfully obvious too, with some new lines echoing specific ways Jews are marginalized, and details like one of the very few adults to take the Baudelaires seriously reading a book about the Weimar Republic, or the ever-so-subtle detail that the Village of Fowl Devotees flag is literally just the Nazi flag with a bird instead of a swastika.
