Peculiar nova eruption inspected by astronomers
An international team of astronomers has employed NASA's Transiting Exoplanet Survey Satellite (TESS) to observe the eruption of Nova Vulpeculae 2021. Results of the observational campaign, published November 8 on the pre-print server arXiv, provide.....»»
How climate change is messing up the ocean"s biological clock, with unknown long-term consequences
Every year in the mid-latitudes of the planet, a peculiar phenomenon known as the phytoplankton spring bloom occurs. Visible from space, spectacular large and ephemeral filament-like shades of green and blue are shaped by the ocean currents......»»
Astronomers reveal a new link between water and planet formation
Researchers have found water vapor in the disk around a young star exactly where planets may be forming. Water is a key ingredient for life on Earth and is also thought to play a significant role in planet formation, yet until now, astronomers have n.....»»
Variable star V708 Car has an unusual chemical composition, study finds
An international team of astronomers has performed spectroscopic observations of a variable star known as V708 Car. Results of the observational campaign, reported in a paper published February 20 on the pre-print server arXiv, indicate that this sta.....»»
Asteroid impacted by spacecraft is reshaped like an M&M ‘with a bite taken out’
In 2022, NASA deliberately crashed a spacecraft into an asteroid. Now astronomers have found that the impact may have reshaped the asteroid significantly......»»
Astronomers detect an extremely red supermassive black hole in the early universe growing in the shadows
Analyzing images from the James Webb Space Telescope (JWST), a group of astronomers led by Dr. Lukas Furtak and Prof. Adi Zitrin from Ben-Gurion University of the Negev has detected an extremely red, gravitationally lensed supermassive black hole in.....»»
Observations explore radio jet of a powerful quasar
European astronomers have conducted very long baseline interferometric (VLBI) observations of a radio jet structure in a powerful quasar known as PKS 2215+020. The collected VLBI data provide important insights into the properties of this jet, sugges.....»»
Further study of bright gamma-ray burst GRB 230307A shows it was caused by neutron stars merging
An international team of astronomers and astrophysicists has found evidence that the bright gamma-ray burst GRB 230307A observed last year was caused by two neutron stars merging, not from a collapsing massive star. In their study, published in the j.....»»
A mass of 17 billion suns: Growing black hole is the most luminous object ever observed by astronomers
A new study published in Nature Astronomy describes the most luminous object ever observed by astronomers. It is a black hole with a mass of 17 billion Suns, swallowing a greater amount of mass than the sun every single day......»»
Three tiny new moons spotted orbiting Uranus and Neptune
Astronomers have discovered three new tiny moons orbiting the far-off planets Neptune and Uranus of the outer solar system......»»
Astronomers detect a new short-period brown dwarf
While analyzing the data from the Next Generation Transit Survey (NGTS), an international team of astronomers has discovered a new brown dwarf. The newfound object, designated NGTS-28Ab, orbits its host star in just about 30 hours. The finding was re.....»»
This famous supernova remnant is hiding a secret
Astronomers using the James Webb Space Telescope have peered into the famous SN 1987A supernova remnant and found something special inside......»»
Astronomers find first strong evidence of neutron star remnant of exploding star
An international team of astronomers including UCL's (University College London's) Professor Mike Barlow has discovered the first conclusive evidence that a neutron star exists at the center of Supernova 1987A, a star explosion observed 37 years ago......»»
Astronomers observe the effect of dark matter on the evolution of the galaxies
Dark matter comprises around 85% of all the matter in the universe. Although ordinary matter absorbs, reflects and emits light, dark matter cannot be seen directly, which makes its detection difficult. Its existence is inferred from its gravitational.....»»
Study investigates chemical composition of metal-poor star HD 1936
Using the Ankara University Kreiken Observatory (AUKR) in Turkey, astronomers have performed high-resolution spectroscopic observations of a metal-poor star known as HD 1936. Results of the observations campaign, published February 15 on the preprint.....»»
Black hole fashions stellar beads on a string
Astronomers have discovered one of the most powerful eruptions from a black hole ever recorded. This mega-explosion billions of years ago may help explain the formation of a striking pattern of star clusters around two massive galaxies, resembling be.....»»
Smallest star ever observed is part of an exotic binary system
A large international team of astronomers has discovered the smallest known star to date, and found that it is paired with another, somewhat larger star. Their paper is published in the journal Nature Astronomy,......»»
Newly spotted black hole has mass of 17 billion Suns, adding another daily
An accretion disk 7 light-years across powers an exceptionally bright galaxy. Enlarge (credit: ESO/M. Kornmesser) Quasars initially confused astronomers when they were discovered. First identified as sources of radio-fre.....»»
Astronomers are figuring out what causes incredibly bright flashes in space
Some of the oddest cosmic phenomena are short but powerful flashes called fast radio bursts. Now astronomers have observed one before and after it occurred,.....»»
Can astronomers use radar to spot a cataclysmic asteroid?
How can humans protect the Earth from "devastating asteroid and comet impacts?" According to the National Academies and their 2023-2032 Planetary Science and Astrobiology Decadal Survey, ground-based astronomical radar systems will have a "unique rol.....»»
Astronomers investigate the atmosphere of a nearby cold brown dwarf
Using the James Webb Space Telescope (JWST), astronomers have observed a nearby cold brown dwarf designated WISEPA J182831.08+265037.8 (or WISE 1828 for short). The observations delivered important insights into the composition of the object's atmosp.....»»
