Stars Are Heavier Than We Thought

A team of University of Copenhagen astrophysicists has arrived at a major result regarding star populations beyond the Milky Way.

Captured by the Mosaic camera on the Nicholas U. Mayall 4-meter Telescope at the Kitt Peak National Observatory (KPNO), a Program of NSF's NOIRLab, the spiral galaxy NGC 2403, also known as Caldwell 7, highlights the dynamic birth and death of stars.

This NASA Hubble Space Telescope image finds the large spiral galaxy, NGC 3227, wrapped in a turbulent gravitational dance with its companion, the elliptical galaxy NGC 3226.

NGC 3718 is a highly disturbed spiral galaxy with an unusual, warped shape that looks a bit like a plump letter "s" from Earth, with a thin thread of dark dust snaking through it.

The Hickson Compact Group 40

NASA is celebrating the Hubble Space Telescope's 32nd birthday with a stunning look at an unusual close-knit collection of five galaxies, called The Hickson Compact Group 40.

This new NASA Hubble Space Telescope image of IC 4271, also known as Arp 40, is a curious pair of spiral galaxies some 800 million light-years away.

This striking pair is an elliptical galaxy NGC 541 and an unusual star-forming, irregular dwarf galaxy known as Minkowski's Object (the bluish object to the lower left of NGC 541).

'Pursuit of the universe's expansion rate began in the 1920s with measurements by astronomers Edwin P. Hubble and Georges LemaƮtre.

This new NASA Hubble Space Telescope image spotlights the giant elliptical galaxy, UGC 10143, at the heart of galaxy cluster, Abell 2147, about 486 million light-years away in the head of the serpent, the constellation Serpens.

Chandra X-ray Image of NGC 3344

This galaxy is part of a large survey of more than 100 galaxies conducted by Chandra that looked for evidence of growing black holes.

Spiral Galaxy IC 342 AKA Caldwell 5

Spiral galaxy IC 342, also known as Caldwell 5, is located approximately 11 million light-years from Earth.

Explosion On A White Dwarf Observed

When stars like our Sun use up all their fuel, they shrink to form white dwarfs.

The spiral galaxy M91 fills the frame of this Wide Field Camera 3 observation from the NASA/ESA Hubble Space Telescope.

The interacting galaxy pair NGC 1512 and NGC 1510 take center stage in this image from the Dark Energy Camera

NASA's Hubble Space Telescope has uncovered a witness at the scene of a star's explosive death: a companion star previously hidden in the glare of its partner's supernova.

A rare and enigmatic outburst from a galaxy 236 million light-years away may have been sparked by a magnetic reversal, a spontaneous flip of the magnetic field surrounding its central black hole.

The ultra-diffuse galaxy GAMA 526784 appears as a tenuous patch of light in this image from the NASA/ESA Hubble Space Telescope.

Chandra X-ray Image Of NGC 4258

NGC 4258 is a spiral galaxy about 25 million light years from Earth, also known as M106.

Astronomers have discovered a new kind of stellar explosion that could be commonplace in the universe and may change our understanding of how eruptions in stars occur.

Ever since they were discovered in 2018, fast blue optical transients (FBOTs) have utterly surprised and completely confounded both observational and theoretical astrophysicists.
