Stellar murder: When stars destroy and eat their own planets
Our sun is both our best friend and our worst enemy. On the one hand, we owe our very existence to our star. Earth and the other planets in the solar system formed out of the same cloud of gas and dust as the sun......»»
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.....»»
The first 3D view of the formation and evolution of globular clusters
A study published in Astronomy & Astrophysics marks a significant milestone in our understanding of the formation and dynamical evolution of multiple stellar populations in globular clusters (spherical and very compact stellar agglomerates typically.....»»
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.....»»

Astronomers predict the orbits of potentially hazardous comets from meteor showers
Comets have long been seen as omens and portents, and it's easy to understand why. They first appear as faint smudges of light in the sky, sometimes fading soon after and sometimes becoming brighter than the planets, with a long, glowing tail. They h.....»»
Why NASA"s SPHEREx mission will make "Most colorful" cosmic map ever
NASA's SPHEREx mission won't be the first space telescope to observe hundreds of millions of stars and galaxies when it launches no later than April 2025, but it will be the first to observe them in 102 colors......»»
Research reveals delayed evolutionary origin of Asteriidae sea stars
A study published in PeerJ has reshaped our understanding of the evolutionary history of sea stars, particularly the family Asteriidae. The study, titled "Phylogenetic and taxonomic revisions of Jurassic sea stars support a delayed evolutionary origi.....»»
Astrophysics study explores turbulence in molecular clouds
On an airplane, motions of the air on both small and large scales contribute to turbulence, which may result in a bumpy flight. Turbulence on a much larger scale is important to how stars form in giant molecular clouds that permeate the Milky Way......»»
Astrophysicists measure "dance" of electrons in the glow from exploding neutron stars
The temperature of elementary particles has been observed in the radioactive glow following the collision of two neutron stars and the birth of a black hole. This has, for the first time, made it possible to measure the microscopic, physical properti.....»»
How life began on Earth: Model suggests ancient Earth had organic-rich atmosphere
The key to unlocking the secrets of distant planets starts right here on Earth. Researchers at Tohoku University, the University of Tokyo, and Hokkaido University have developed a model that considers various atmospheric chemical reactions to estimat.....»»
