Starburst Galaxy

The sparkling scene depicted in this NASA/ESA Hubble Space Telescope image is of the spiral galaxy NGC 5248, located 42 million light-years from Earth in the constellation Boötes. It is also known as Caldwell 45. The Caldwell catalog holds visually interesting celestial objects that are not as commonly observed by amateur astronomers as the more […]

Hubble's Wide Field Camera 3 (WFC3) has taken a striking new image of the grand design spiral galaxy NGC 5248.

Scientists think they know what's causing this unprecedented brightening.

The James Webb Space Telescope caught the Magellanic-like galaxy NGC 4449 is undergoing an intense bout of star formation.

Star death and birth both contribute to driving material out of a galaxy.

Astronomers have discovered a flare erupting from a highly magnetic "dead star" outside the solar system for the first time. The magnetar flare lit up the...

More evolved galaxies demonstrate a greater range of stellar motions compared to the orderly, circular orbits of stars like our sun in the Milky Way.

Astronomers using the NASA/ESA/CSA James Webb Space Telescope have captured a spectacular image of I Zwicky 18 (I Zw 18 for short), the archetypal extremely metal-poor, star-forming, blue compact dwarf galaxy in the constellation of Ursa Major.

A stunning new pair of images from the James Webb Space Telescope show a new view of a familiar galaxy: Messier 82.

Data from a recent stellar explosion showed a mathematical discrepancy, possibly providing rare evidence of a black hole forming right before our very eyes

High-energy particles from space constantly bombard Earth at near light speed, but what are their origins?

This new NASA Hubble Space Telescope image shows ESO 185-IG013, a luminous blue compact galaxy (BCG). BCGs are nearby galaxies that show an intense burst of star formation. They are unusually blue in visible light, which sets them apart from other high-starburst galaxies that emit more infrared light. Astrophysicists study BCGs because they provide a […]

At the heart of the image is a bright young star surrounded by six prominent spokes of light.

The James Webb Space Telescope has released a stunning new image revealing a massive star forming region of the Milky Way galaxy known as N79.

The James Webb Space Telescope has zoomed in on N79, a 1,630-light-year-wide star birthing complex in the Large Magellanic Cloud, to produce a stunning image...

Giant clouds of cold gas in NGC 4945, were blasted through the spiral galaxy when its central black hole erupted 5 million years ago.

Researchers at NASA's Goddard Space Flight Center in Greenbelt, Maryland, have discovered X-ray activity that sheds light on the evolution of galaxies. The X-rays outline giant clouds of cold gas in the nearby spiral galaxy NGC 4945. The gas appears to have blasted through the galaxy after its central supermassive black hole erupted some 5 […]

Massive rings in space known as odd radio circles may be sculpted by a shock wave of screaming winds created by the explosions of stars, according to a new...

The Telescope Array in Utah's West Desert picked up a rare particle with 244 EeV energy.

The Gemini South telescope observed two spiral galaxies that smashed together around a billion years ago. The aftermath harbors the closest supermassive...
