Even stars doomed to die as supernovae can have planets
Ninety percent of all exoplanets discovered to date (there are now more than 5,000 of them) orbit around stars the same size or smaller than our sun. Giant stars seem to lack planetary companions, and this fact has serious implications for how we und.....»»
Double-peaked supernovae offer clues to pre-supernova outbursts
New research helps in understanding the evolution and final stages of massive stars, the role of binary interactions, and the mechanisms behind mass loss, which ultimately affect the properties of the resulting supernova and its remnant. This work al.....»»
Webb discovers six new "rogue worlds" that provide clues to star formation
Rogue planets, or free-floating planetary-mass objects (FFPMOs), are planet-sized objects that either formed in interstellar space or were part of a planetary system before gravitational perturbations kicked them out......»»
Hubble zooms into the rosy tendrils of Andromeda
Clusters of stars set the interstellar medium ablaze in the Andromeda galaxy about 2.5 million light-years away. Also known as M31, Andromeda is the Milky Way's closest major galaxy. It measures approximately 152,000 light-years across and, with almo.....»»
iPhone 16 Glowtime is coming, AirTags save the day on the AppleInsider Podcast
We're days away from the launch of the iPhone 16, but the question is whether Apple will make it to September 9 considering that it is — yet again — said to be doomed because Luca Maestri is leaving.Apple's Glowtime event logoThe latest reason fo.....»»
Hubble observes an oddly organized satellite galaxy
Andromeda III is one of at least 13 dwarf satellite galaxies in orbit around the Andromeda galaxy, or Messier 31, the Milky Way's closest grand spiral galactic neighbor. Andromeda III is a faint, spheroidal collection of old, reddish stars that appea.....»»
Hubble traces star formation in nearby nebula NGC 261
NGC 261 blooms a brilliant ruby red against a myriad of stars in this new image from NASA's Hubble Space Telescope. Discovered on Sept. 5, 1826 by Scottish astronomer James Dunlop, this nebula is located in one of the Milky Way's closest galactic com.....»»
Nissan welcomes Reggie Bush to Heisman House after he reclaimed his trophy
USC legend Reggie Bush stars in college football campaign four months after the Heisman Trophy Trust returned his trophy, which he forfeited in the wake of sanctions......»»
Novel features of r-process nucleosynthesis shed light on origin of heavy elements
In a study published in The Astrophysical Journal, scientists have proposed the features of the rapid neutron capture process (r-process) nucleosynthesis in a novel scenario: common envelop jet supernovae (CEJSNe). The study sheds new light on the or.....»»
Cast negotiations underway for Ted Lasso season 4, production expected to start early next year
For fans of Ted Lasso, this latest development is the most concrete news yet that season four of Apple’s hit comedy series is going ahead. Deadline reports that cast negotiations are underway, with contract options already executed for stars Han.....»»
Watch a star get destroyed by a supermassive black hole in the first simulation of its kind
Giant black holes in the centers of galaxies like our own Milky Way are known to occasionally munch on nearby stars......»»
Hubble spots the Tucana Dwarf in the dark
A splatter of stars glows faintly at almost 3 million light-years away in this new image from NASA's Hubble Space Telescope. Known as the Tucana Dwarf for lying in the constellation Tucana, this dwarf galaxy contains a loose bundle of aging stars at.....»»
Sennheiser Accentum headphones, already a bargain, are $48 off today

The evolution of the Trappist-1 planetary system
Planets are bodies that orbit a star and have sufficient gravitational mass that they form themselves into roughly spherical shapes that, in turn, exert gravitational force on smaller objects around them, such as asteroids and moons......»»
New simulations shed light on stellar destruction by supermassive black holes
Monash University astronomers have contributed to a breakthrough in understanding the dramatic fate of stars that wander too close to supermassive black holes at the centers of galaxies......»»
Hubble spots a cluster of emission nebulae within the Large Magellanic Cloud
A bubbling region of stars both old and new lies some 160,000 light-years away in the constellation Dorado. This complex cluster of emission nebulae is known as N11, and was discovered by American astronomer and NASA astronaut Karl Gordon Henize in 1.....»»
A galactic "conspiracy" disproven: Dark matter and stars not interacting as previously thought
A longstanding 'conspiracy' in astronomy—that stars and dark matter are interacting in inexplicable ways—has been overturned by an international team of astronomers, in a paper in Monthly Notices of the Royal Astronomical Society......»»
Exoplanets may contain more water than previously thought
We know that the Earth has an iron core surrounded by a mantle of silicate bedrock and water (oceans) on its surface. Science has used this simple planet model until today for investigating exoplanets—planets that orbit another star outside our sol.....»»
Dark Matter scores season two renewal on Apple TV+
One of 2024’s most popular Apple TV+ series, Dark Matter, has scored a season two renewal. The sci-fi thriller is bringing back showrunner and author Blake Crouch, plus stars Joel Edgerton and Jennifer Connelly, to continue exploring the mysteries.....»»
Tracking a newly discovered hypervelocity star spotted by citizen scientists
It may seem like the sun is stationary while the planets in its orbit are moving, but the sun is actually orbiting around the Milky Way galaxy at an impressive rate of about 220 kilometers per second—almost half a million miles per hour......»»
