Scientists from Ireland and France today announced a major new finding about how matter behaves in the extreme conditions of the Sun’s atmosphere. The scientists…
Where did the Earth’s water come from? Although comets, with their icy nuclei, seem like ideal candidates, analyses have so far shown that their water…
A neutron star merger without an observed gamma-ray burst has been discovered using NASA’s Chandra X-ray Observatory. This result gives astronomers another way to track…
Small, hardy planets packed with dense elements have the best chance of avoiding being crushed and swallowed up when their host star dies, new research…
Massive clusters of galaxies, some with more mass than a hundred Milky Way galaxies, have been detected from cosmic epochs as early as about three…
NASA’s Spitzer Space Telescope has revealed that some of the universe’s earliest galaxies were brighter than expected. The excess light is a byproduct of the…
Blue supergiants are rock ‘n’ roll: they live fast and die young. This makes them rare and difficult to study. Before space telescopes were invented,…
Astronomers have put together the largest and most comprehensive “history book” of galaxies into one single image, using 16 years’ worth of observations from NASA’s…
The study of a tiny grain of stardust — older than our solar system — is shining new light on how planetary systems are formed….
Small stellar systems like dwarf galaxies are suggested to be the main building blocks of our Galaxy. However, it is unclear how many and what…
Astronomers using NASA’s Hubble Space Telescope say they have crossed an important threshold in revealing a discrepancy between the two key techniques for measuring the…
Scientists in the VERITAS (Very Energetic Radiation Imaging Telescope Array System) Collaboration have published a paper in Nature Astronomy journal detailing the results of their…
The first type of molecule that ever formed in the universe has been detected in space for the first time, after decades of searching. Scientists…
The Event Horizon Telescope (EHT) — a planet-scale array of eight ground-based radio telescopes forged through international collaboration — was designed to capture images of…
The closest exoplanet to us, if we include only single stars like the Sun, is the planet around Barnard’s Star, Barnard’s Star-b (“BSb”). (The planet…
A black hole and its shadow have been captured in an image for the first time, a historic feat by an international network of radio…
Metallic asteroids are thought to have started out as blobs of molten iron floating in space. As if that’s not strange enough, scientists now think…
