Hubble snaps an image of a galaxy in our cosmic backyard

By Georgina Torbet Published January 15, 2023

Every week, astronomers working with the Hubble Space Telescope share an image of space collected by the telescope. This week, the Hubble image is of a nearby galaxy called LEDA 48062, located just 30 million light-years away from our own galaxy — making it practically next door in cosmic terms.

The galaxy was observed as part of a project called Every Known Nearby Galaxy, which aims to use Hubble to study every galaxy within 10 megaparsecs (33 million light-years) of the Milky Way. “By getting to know our galactic neighbors, astronomers can determine what types of stars reside in various galaxies and also map out the local structure of the universe,” Hubble scientists write.

LEDA 48062 is the faint, sparse, amorphous galaxy on the right side of the image, and it is accompanied by a more sharply defined neighbor on the left – the large, disk-like lenticular galaxy UGC 8603. A smattering of more distant galaxies litters the background while a handful of foreground stars shine brightly throughout the image. ESA/Hubble & NASA, R. Tully

In this image, LEDA 48062 is the loose, fuzzy shape to the right of the frame. You can see many other galaxies in the image as well, including the clearly defined bar shape on the left — which is a lenticular galaxy called UGC 8603.

Galaxies come in three main types: spiral galaxies like our Milky Way, with a central bulge surrounded by a flat disk with arms reaching out in a spiral shape; elliptical galaxies, which are smooth and have an even distribution of light, making them appear like an ellipsis; and lenticular galaxies, which are halfway between these other two with a central bulge but no spiral structure.

There is also a fourth class of galaxy called irregular galaxies, which do not have a clear structure. These are often galaxies that started out as one of the three types above but were pulled into an irregular shape by the forces of gravity. This can happen when two galaxies are merging as their gravitational interactions can pull them into strange shapes.

NASA’s new telescope can see 100 times more sky than Hubble in a single shot

NASA just launched a $4 billion telescope to map billions of galaxies

NASA Roman Telescope Launch Featured

The Hubble telescope has an almost legendary status. Over the last three decades, Hubble gave us some of the most spectacular close-ups of the universe ever captured, and now, NASA’s newest space telescope wants to see the bigger picture. The Nancy Grace Roman Space Telescope successfully launched aboard a SpaceX Falcon Heavy from Kennedy Space Center in Florida at 7:26 a.m. EDT on August 30. Roman is now beginning a roughly three-month journey toward the Sun-Earth L2 point, nearly a million miles away, where it will spend its primary five-year mission surveying huge portions of the cosmos.

Roman carries a 2.4-meter primary mirror, the same diameter as Hubble’s, but its Wide Field Instrument can capture a field of view at least 100 times larger than Hubble’s. NASA expects it to use that combination of sharpness and scale to map billions of galaxies, study dark matter and dark energy, and discover enormous numbers of previously unknown worlds.

NASA built the Roman Space Telescope to study dark matter, but it can also help protect Earth from killer asteroids

The Nancy Grace Roman Space Telescope wasn't built to hunt asteroids, but it turns out to be great at it.

NASA is about to launch a telescope built to unlock some of the universe's biggest mysteries, and it turns out that same design could help protect Earth along the way.

The Nancy Grace Roman Space Telescope is set to launch from Kennedy Space Center on August 30, 2026, with a primary mission focused on studying dark matter and dark energy - the invisible forces shaping galaxies and cosmic expansion. Researchers now say its unique design also makes it unexpectedly effective at spotting dangerous asteroids headed our way (via MIT Technology Review).

Space is becoming Bezos and Musk’s next data center site, and we have every reason to worry

The AI boom is coming for the night sky

How Vast's space station will look in orbit.

AI data centers already consume vast amounts of electricity and water on Earth, so Silicon Valley has begun looking somewhere considerably more spacious... literally.

Elon Musk's SpaceX and Jeff Bezos' Blue Origin, along with several other companies, have proposed enormous constellations of satellites designed to operate as orbital data centers. However, environmental groups and former space officials are now warning that putting them into orbit at the proposed scale could have severe consequences for Earth's atmosphere and the night sky.
