| Dead star's cannibalism of its planetary system is most far-reaching ever witnessed Posted: 15 Jun 2022 06:13 PM PDT The violent death throes of a nearby star so thoroughly disrupted its planetary system that the dead star left behind -- known as a white dwarf -- is sucking in debris from both the system's inner and outer reaches, astronomers report. |
| Astronomers find evidence for most powerful pulsar in distant galaxy Posted: 15 Jun 2022 06:13 PM PDT Astronomers using data from the VLA Sky Survey have discovered one of the youngest known neutron stars -- possibly as young as only 14 years. The dense remnant of a supernova explosion was revealed when bright radio emission powered by the pulsar's powerful magnetic field emerged from behind a thick shell of debris from the explosion. |
| Gaia Data Release 3: 'Complete step change' in understanding of our Universe Posted: 15 Jun 2022 06:13 PM PDT Space scientists have discovered a 'super Jupiter' orbiting a white dwarf, detected using direct observations with the European Space Agency (ESA)'s Gaia mission. |
| Tracing the remnants of Andromeda's violent history Posted: 15 Jun 2022 06:13 PM PDT A detailed analysis of the composition and motion of more than 500 stars revealed conclusive evidence of ancient a collision between Andromeda and a neighboring galaxy. The findings improve our understanding of the events that shape galaxy evolution. |
| Posted: 15 Jun 2022 06:13 PM PDT Astronomers have imaged the debris disk of the nearby star HD 53143 at millimeter wavelengths for the first time, and it looks nothing like they expected. Based on early coronagraphic data, scientists expected ALMA to confirm the debris disk as a face-on ring peppered with clumps of dust. Instead, the observations took a surprise turn, revealing the most complicated and eccentric debris disk observed to date. |
| Young galaxy’s coming of age: Early galaxies may be surprisingly big and complex Posted: 15 Jun 2022 06:13 PM PDT Scientists have observed a significant amount of cold, neutral gas in the outer regions of the young galaxy A1689-zD1, as well as outflows of hot gas coming from the galaxy's center. These results may shed light on a critical stage of galactic evolution for early galaxies, where young galaxies begin the transformation to be increasingly like their later, more structured cousins. |
| A weird star produced the fastest nova on record Posted: 15 Jun 2022 06:13 PM PDT A research team has observed the fastest nova ever. They hope to find answers to not only the nova's many baffling traits, but to larger questions about our solar system and the universe. |
| Astronomers discover a multiplanet system nearby Posted: 15 Jun 2022 06:12 PM PDT Astronomers discovered a multiplanet system just 33 light-years from Earth, making it one of the closest known multiplanet systems. The system likely hosts at least two terrestrial, Earth-sized planets. |
| New maps of asteroid Psyche reveal an ancient world of metal and rock Posted: 15 Jun 2022 12:47 PM PDT Astronomers have mapped the surface properties of the asteroid Psyche, revealing a landscape of metal and rock. |
| The tarantula's cosmic web: Astronomers map violent star formation in nebula outside our galaxy Posted: 15 Jun 2022 10:46 AM PDT Astronomers have unveiled intricate details of the star-forming region 30 Doradus, also known as the Tarantula Nebula, using new observations from the Atacama Large Millimeter/submillimeter Array (ALMA). Now we can see the nebula in a new light, with wispy gas clouds that provide insight into how massive stars shape this region. |
| To find a planet, look for the signatures of planet formation Posted: 15 Jun 2022 10:46 AM PDT Finding forming planets is a tough but important job for astronomers: Only three planets have ever been discovered caught in the process of forming, and the most recent of these was found just weeks ago. |
| Previously hidden protoclusters could reveal new details of galaxy evolution Posted: 15 Jun 2022 08:32 AM PDT The ancestors of some of the largest galaxy clusters have been hiding in plain sight. New work demonstrates a new technique for identifying the precursors of the most extreme galactic environments. |
| Near-sun comet roasted to death Posted: 15 Jun 2022 07:29 AM PDT Astronomers using a fleet of world leading telescopes on the ground and in space have captured images of a periodic rocky near-Sun comet breaking apart. This is the first time such a comet has been caught in the act of disintegrating and could help explain the scarcity of such periodic near-Sun comets. |
| No signs (yet) of life on Venus Posted: 14 Jun 2022 09:26 AM PDT The unusual behavior of sulphur in Venus' atmosphere cannot be explained by an 'aerial' form of extra-terrestrial life, according to a new study. |
