Professor John Terning and Dr. Christopher Verhaaren from the University of California, Davis, have a new candidate for dark matter — a dark monopole...
Astronomers using the Low-Frequency Array (LOFAR) telescope network have detected a vast ridge of radio emission connecting the merging galaxy clusters...
Markarian 1216 (Mrk 1216 for short) is a compact elliptical galaxy about 316 million light-years away. New data from NASA’s Chandra X-ray Observatory...
Astronomers using the 8-m Subaru Telescope have identified 1,824 new supernova candidates, including 58 Type Ia supernovae over 8 billion light-years away.

The NASA/ESA Hubble Space Telescope has produced this beautiful image of an elliptical galaxy called Messier 59.
This Hubble image shows the elliptical...
NASA has released a beautiful image snapped by the NASA/ESA Hubble Space Telescope of the spiral galaxy Messier 90.
This Hubble image shows the spectacular...
Gravitational waves are ‘ripples’ in space-time caused by some of the most violent and energetic processes in the Universe. Albert Einstein predicted...
New data from Spitzer and Hubble space telescopes show that in a few specific wavelengths of infrared light, some of the first galaxies to form in the...
A team of astronomers from MIT has observed evidence that the Universe’s first stars exploded as asymmetric supernovae, strong enough to scatter heavy...
On April 25 and 26, 2019, NSF’s Laser Interferometer Gravitational-Wave Observatory (LIGO) and the European-based Virgo detector registered two new gravitational...
A spectacular new image from the NASA/ESA Hubble Space Telescope shows SPT-CL J0615-5746, a very massive group of galaxies located approximately 7.7 billion...
Professor Avi Loeb of the Harvard-Smithsonian Center for Astrophysics and colleagues have proposed a new test for inflation, the theory that our Universe...
Measurements of today’s expansion rate do not match the rate that was expected based on how the Universe appeared shortly after the Big Bang over 13...
In 2018, a team of astronomers from the United States and Canada discovered that an ultra-diffuse galaxy called NGC 1052-DF2 (DF2 for short) contains virtually...
When the Universe was still very young, only a few kinds of atoms existed. Astrophysicists believe that around 100,000 years after the Big Bang, ionized...
A team of astronomers using the Gemini-South telescope has discovered one of the oldest stellar clusters in the Milky Way. The team’s results date the...
Astronomers using the Subaru Telescope have discovered 83 quasars in the distant Universe, from a time when the Universe was less than 10% of its present...
About a third of the normal matter — meaning hydrogen, helium and other elements — created shortly after the Big Bang is not seen in the present-day...
