Astronomers discovered only relatively recently that black hole jets emit X-rays, and how the jets accelerate particles to this high-energy state is a...
Astronomers using the NASA/ESA Hubble Space Telescope have obtained a remarkable new view of the small spiral galaxy NGC 298.
This Hubble image shows NGC...
New images that combine data from the NASA/ESA/CSA James Webb Space Telescope and several space- and ground-based telescopes show spiral galaxies NGC 1672...
Symmetry is a tidy and attractive idea that falls apart in our untidy Universe. Indeed, since the 1960s, some kind of broken symmetry has been required...
The NASA/ESA Hubble Space Telescope has captured a striking new photo of a jellyfish spiral galaxy called JW39.
This Hubble image shows JW39, a jellyfish...
The gravitationally lensed Supernova (SN) Refsdal was discovered by University of Minnesota astronomer Patrick Kelly in 2014 in the field of MACS J1149.6+2223,...
Glacial cycles during the Early Pleistocene epoch are characterized by a dominant 41,000-year periodicity and amplitudes smaller than those of glacial...
AT2021lwx occurred nearly 8 billion years ago and was more than 10 times brighter than any known supernova explosion. The event was likely caused by the...
Fast radio bursts (FRBs) are brief flashes of radio waves from distant galaxies that are probably emitted by neutron stars. Some FRBs repeat, which enables...
Astronomers at Newcastle University and Colby College have developed a new technique to determine how likely it is that two galaxies are very close together...
The Hubble team has released a beautiful new image of two massive galaxies, NGC 545 and NGC 547, collectively known as Arp 308.
This Hubble image shows...
eMACS J1823.1+7822 has so much mass that it acts as a gravitational lens, causing light from distant galaxies to bend around it.
This Hubble image shows...
Astronomers using the NASA/ESA Hubble Space Telescope have captured a beautiful new image of the lenticular galaxy NGC 5283.
This Hubble image shows NGC...
Centaurus A is located 13 million light-years away in the constellation of Centaurus, and represents the fifth brightest galaxy in the sky.
This composite...
Astronomers using the NASAESA Hubble Space Telescope have captured a detailed image of a lenticular galaxy called NGC 3489.
This Hubble image shows NGC...
The NASA/ESA Hubble Space Telescope has produced an outstanding image of the jellyfish galaxy JO175.
This Hubble image shows JO175, a jellyfish galaxy...
In 2017, astronomers from the Event Horizon Telescope (EHT) Collaboration captured the first image of a black hole by coordinating radio dishes around...
Fast radio bursts (FRBs) are microsecond-millisecond flashes of radio waves that are detectable over extragalactic distances; some FRB sources repeat....
The seven galaxies highlighted in this new image from the NASA/ESA/CSA James Webb Space Telescope have been confirmed to be at a distance that astronomers...
