Radio observations of a cold, dense cloud of molecular gas reveal more than a dozen unexpected molecules. Scientists have discovered a vast, previously unknown reservoir…
Using the Atacama Large Millimeter/submillimeter Array (ALMA), in which the European Southern Observatory (ESO) is a partner, a team of astronomers have directly measured winds…
Cooperative operations between a solar observation satellite and a sounding-rocket telescope have measured the magnetic field strength in the photosphere and chromosphere above an active…
Discrepancies in the Hubble constant, which describes how fast the universe is expanding, have vexed astronomers for years. Values predicted from observations of the early…
When NASA’s Parker Solar Probe sent back the first observations from its voyage to the Sun, scientists found signs of a wild ocean of currents…
Astronomers have discovered new hints of a giant, scorching-hot planet orbiting Vega, one of the brightest stars in the night sky. The research, published this…
From a black hole to the South Pole: Scientists identify first neutrino from a tidal disruption event. Tracing back a ghostly particle to a shredded…
University of Chicago study finds way that hot, rocky planets in other systems could form and keep atmospheres. An atmosphere is what makes life on…
An international research team with members from ETH has developed a new method for directly imaging smaller planets in the habitable zone of a neighboring…
Data from the NASA spacecraft’s journey to Jupiter suggests that Mars may be shedding dust into interplanetary space. Look up to the night sky just…
Located around 5000 light-years away in the constellation of Cygnus (The Swan), Abell 78 is an unusual type of planetary nebula. After exhausting the nuclear…
Astronomers may have discovered the most distant jet emitting X-rays. The source of this jet is a rapidly growing supermassive black hole, or quasar, located…
The weathering of silicate rocks plays an important role to keep the climate on Earth clement. Scientists led by the University of Bern and the…
The interplanetary interloper won’t come closer than 1.25 million miles to Earth, but it will present a valuable scientific opportunity for astronomers. The largest asteroid…
The Earth-sized exoplanet may have lost its original atmosphere but gained a second one through volcanism. Orbiting a red dwarf star 41 light-years away is…
On December 6, 2016, a high-energy particle hurtled to Earth from outer space at close to the speed of light. The particle, an electron antineutrino,…
Scientists have long theorized that supermassive black holes can wander through space—but catching them in the act has proven difficult. Now, researchers at the Center…
Researchers at UCL have solved a major piece of the puzzle that makes up the ancient Greek astronomical calculator known as the Antikythera Mechanism, a…
