Stars can eat their planets, and spit them back out again
As tragic as it is, engulfment of a planetary object by its stellar parent is a common scenario throughout the universe. But it doesn't have to end in doom. A team of astrophysicists have used computer simulations to discover that planets can not onl.....»»
Gel coatings could make it easier to eat fiber-rich foods
Fiber is something that most of us get far too little of. To change that, we need to actually enjoy eating it. Food researchers from the University of Copenhagen have now invented a "disguise" that solves the problem of the dry and gritty mouth feel.....»»
Predicting the next supernova explosion: New simulations reveal the physics of supernova shock breakout
Stars with masses between 10 and 30 times that of the sun, in their final evolutionary stages, form an iron core that ultimately collapses into a neutron star. This collapse releases a tremendous amount of gravitational potential energy through neutr.....»»
First pairs of white dwarf–main sequence binaries discovered in clusters shine new light on stellar evolution
Astronomers at the University of Toronto (U of T) have discovered the first pairs of white dwarf and main sequence stars—"dead" remnants and "living" stars—in young star clusters. Described in a new study published in The Astrophysical Journal, t.....»»
Famous Star Hasn’t Formed Planets, and We Don’t Know Why
The nearby star Vega, featured in the 1997 movie Contact, appears to have a smooth disk devoid of giant planets for reasons we can’t explain.....»»
A bit of bling helps insects dazzle their predators, high-speed camera study shows
Wearing a bright outfit covered in shiny sequins is a sure-fire way to attract attention. Just think of stars on stage—Beyonce, Taylor Swift or Harry Styles—their bedazzled outfits catch the lights, flashing and sparkling as they dance in concert.....»»
Simulations reveal black holes inherit magnetic fields from parent stars
Black holes are one of the most enigmatic stellar objects. While best known for swallowing up their surroundings into a gravity pit from which nothing can escape, they can also shoot off powerful jets of charged particles, leading to explosive bursts.....»»
Physicists think they may know the key to unlocking time travel
Imagine a thread so thin it’s invisible to the naked eye but packed with the mass of thousands of stars. This isn’t science fiction—it’s the … The post Physicists think they may know the key to unlocking time travel appeared first on BG.....»»
Hit sci-fi series Silo returns for season two today
One of the biggest hits on Apple TV+ returns for season two today: the sci-fi series Silo, based on the . Rebecca Ferguson stars as Juliette, an engineer who seeks to break out of the underground silo in which everyone is living. Following the exp.....»»
Scientists compile library for evaluating exoplanet water
By probing chemical processes observed in the Earth's hot mantle, Cornell scientists have started developing a library of basalt-based spectral signatures that not only will help reveal the composition of planets outside of our solar system but could.....»»
Scientists identify flaw in astrophysics models of massive stars and supernovae
An international team of researchers has uncovered evidence that astrophysics models of massive stars and supernovae are inconsistent with observational gamma-ray astronomy......»»
Star"s disappearance in Andromeda marks the birth of a black hole
Massive stars about eight times more massive than the sun explode as supernovae at the end of their lives. The explosions, which leave behind a black hole or a neutron star, are so energetic they can outshine their host galaxies for months. However,.....»»
This trail-tested, road ready Aventon e-bike is $200 off — We gave it 4.5 stars
Along with a host of other Aventon e-bike deals, the Ramblas eMTB e-bike is on sale for $200 off and it's already priced competitively. You need to see it......»»
Examining how stellar threats impact the habitable zone of exoplanets
When we think of exoplanets that may be able to support life, we home in on the habitable zone. A habitable zone is a region around a star where planets receive enough stellar energy to have liquid surface water. It's a somewhat crude but helpful fir.....»»
How many additional exoplanets are in known systems?
One thing we've learned in recent decades is that exoplanets are surprisingly common. So far, we've confirmed nearly 6,000 planets, and we have evidence for thousands more. Most of these planets were discovered using the transit method. though there.....»»
Globular cluster Gran 5 hosts two stellar populations, study finds
Using the Gemini-South telescope, astronomers have performed high-resolution near-infrared spectroscopy of stars in a Galactic globular cluster known as Gran 5. They found that this cluster harbors two stellar populations with different metallicities.....»»
The "27 Club" isn"t true, but it is real—a sociologist explains why myths endure and how they shape reality
There's a certain allure to the notion that some of the world's brightest stars burn out at the age of 27. The so-called 27 Club has captivated the public imagination for half a century. Its members include legendary musicians Jimi Hendrix, Janis Jop.....»»
Observations detect hundreds of possible supergiant stars in two nearby galaxies
Using the Large Sky Area Multi-Object Fiber Spectroscopic Telescope (LAMOST), Chinese astronomers have identified nearly 300 candidate supergiant stars in the Andromeda and Triangulum galaxies. The finding was reported in a research paper published O.....»»
NASA’s monthly skywatching tips include a rare lunar occultation
November is a good month to view many of the planets in our neighborhood, and some folks will also be able to witness a rare lunar occultation......»»
Learning more about supernovae through stardust
Most of the diverse elements in the universe come from supernovae. We are, quite literally, made of the dust of those long-dead stars and other astrophysical processes. But the details of how it all comes about are something astronomers strive to und.....»»
