A Sun-like star located in a galaxy roughly 500 million light-years away is being gradually devoured by a black hole, shedding a mass equal to three Earths on each close pass.
Herbig-harrows are luminous regions surrounding young stars. They form when stellar winds or jets of gas ejected from these stars create shock waves that collide at high speeds with nearby gas and dust.
A special article in honor of Hebrew new year summarizing the creation of the world through the lens of science
The unusual jet structure reveals unique features of the relatively nearby gamma-ray burst that can be studied in better detail than the gamma-wave bursts discovered so far
A new spacecraft called XRISM (X-ray Imaging and Spectroscopy Mission, pronounced "charism") is designed to separate high-energy light into the equivalent of an X-ray rainbow
The Ring Nebula, formed by a star shedding its outer layers, is a classic example of a planetary nebula and is also relatively close to us.
Astronomers at the European Southern Observatory discovered that the star HD 45166 is a neutron star about to become a megastar
This end-of-life phase of red giant stars is relatively short, and the celestial structures that form around them are rare, so the Tobi Pitcher Nebula is an excellent example of a case study in the evolution of a star
The brown dwarf is part of a new pair system that may advance our understanding of the evolution of stars and planets under extreme radiation conditions
"The effect of gravitational waves on pulsars is very weak and difficult to detect, but we built the credibility of the findings over time as we collected more data," said Caterina Cazziano, NANOGrav team member and senior lecturer at Caltech.
A highly unusual burst of high-energy light from a nearby galaxy is linked by scientists to a neutron star merger
NASA's Nancy Grace Roman space telescope, which will be launched in May 2027, will be able to find an astonishing number of 400 Earth-mass stray worlds. Indeed, in the new study, one such candidate has already been identified
SETI researchers have invented a new technique for detecting potential alien radio signals
What could aliens pick up from the radio leak from Earth? How would Earth look to an alien civilization light years away from us?
Protoplanets form from clumps of material in disks around newborn stars. When the planet is still forming, that is, when it is still collecting material, it is called a protoplanet. This is only the third protoplanet discovered
NANOGrav Discovers Stronger Gravitational Waves Than Ever, Apparently Created by Pairs of Supermassive Black Holes
From our own cosmic backyard in the Solar System to distant galaxies toward the dawn of time, the NASA/European Space Agency/CSA James Webb Space Telescope has lived up to its promise to reveal the universe like never before in its first year of scientific activity. To celebrate the end of a year A successful first, a new Web image has been released of a small star-forming region in the Rho Ophiuchi cloud complex
The meteorite components enriched in radioactive isotopes formed in the first 100,000 years or so of the formation of the Solar System within the dense filament. The mother filament may have served as a buffer that protected the young sun and helped capture the radioactive isotopes from the supernova shock wave and channel them into the still forming solar system.
The "Dark Universe" Euclid space telescope is launched on a mission to uncover the deepest mysteries of the cosmos
Akshay Suresh, a graduate student at Cornell University, is leading an unusual scientific activity - a groundbreaking mission called BLIPSS to detect periodic signals emanating from the center of the Milky Way
At the end of 2019, the light of the star dimmed and went from the brightest in the Orion group to the third brightest. Since then it has returned and become even brighter than before
An international team of astronomers has announced the discovery of a second planet in the circumbinary system (where planets orbit two suns) of the rare multiple planet BEBOP-1. This planet was discovered using the transit method and was noticed because it passed in front of the brighter of the two stars on different occasions
A significant development in thin layer technology could possibly improve the sensitivity of gravitational wave detectors.
A team of researchers confirmed Hawking's prediction of evaporating black holes, but extended its application to all large objects in the universe
The galaxy is currently 25 billion light-years away, but when light began to travel from it to us about 12.5 billion years ago, it was much closer, because the universe is expanding
