Hubble Studies Small but Mighty Galaxy

This portrait from the NASA/ESA Hubble Space Telescope puts the nearby galaxy NGC 4449 in the spotlight. The galaxy is situated just 12.5 million light-years away in the constellation Canes Venatici (the Hunting Dogs). It is a member of the M94 galaxy group, which is near the Local Group of galaxies that the Milky Way […]

NASA’s Roman to Peer Into Cosmic ‘Lenses’ to Better Define Dark Matter

A funky effect Einstein predicted, known as gravitational lensing — when a foreground galaxy magnifies more distant galaxies behind it — will soon become common when NASA’s Nancy Grace Roman Space Telescope begins science operations in 2027 and produces vast surveys of the cosmos.

NASA’s Webb ‘UNCOVERs’ Galaxy Population Driving Cosmic Renovation

Astronomers using data from NASA’s James Webb Space Telescope have identified dozens of small galaxies that played a starring role in a cosmic makeover that transformed the early universe into the one we know today. “When it comes to producing ultraviolet light, these small galaxies punch well above their weight,” said Isak Wold, an assistant […]

NASA’s Chandra Sees Surprisingly Strong Black Hole Jet at Cosmic “Noon”

A black hole has blasted out a surprisingly powerful jet in the distant universe, according to a new study from NASA’s Chandra X-ray Observatory and discussed in our latest press release. This jet exists early enough in the cosmos that it is being illuminated by the leftover glow from the big bang itself. Astronomers used […]

Hubble Captures Starry Spectacle

A galaxy ablaze with young stars is the subject of this NASA/ESA Hubble Space Telescope image. Named NGC 685, this galaxy is situated about 64 million light-years away in the constellation Eridanus (the River). NGC 685 is a barred spiral because its feathery spiral arms sprout from the ends of a bar of stars at […]

NASA’s IXPE Obtains First X-ray Polarization Measurement of Magnetar Outburst

What happens when the universe’s most magnetic object shines with the power of 1,000 Suns in a matter of seconds? Thanks to NASA’s IXPE (Imaging X-ray Polarimetry Explorer), a mission in collaboration with ASI (Italian Space Agency), scientists are one step closer to understanding this extreme event.  Magnetars are a type of young neutron star […]

3 Black Holes Caught Eating Massive Stars in NASA Data

Black holes are invisible to us unless they interact with something else. Some continuously eat gas and dust, and appear to glow brightly over time as matter falls in. But other black holes secretly lie in wait for years until a star comes close enough to snack on. A new study using space and ground-based […]

NASA’s Webb Rounds Out Picture of Sombrero Galaxy’s Disk

After capturing an image of the iconic Sombrero galaxy at mid-infrared wavelengths in late 2024, NASA’s James Webb Space Telescope has now followed up with an observation in the near-infrared. In the newest image, the Sombrero galaxy’s huge bulge, the tightly packed group of stars at the galaxy’s center, is illuminated, while the dust in […]

Hubble Filters a Barred Spiral

This NASA/ESA Hubble Space Telescope image features a luminous tangle of stars and dust called the barred spiral galaxy NGC 1385, located about 30 million light-years away. Hubble released an earlier image of NGC 1385, but the two images are notably different. This more recent image has far more pinkish-red and umber shades, whereas cool […]
