This behemoth, with a diameter of 230 light-years, is 10 times more massive than a typical globular cluster. Despite all these stars, scientists released a study in 2018 that said Omega Centauri probably is not home to life. Stars pack so tightly inside Omega Centauri that the average distance between stars in the c...

The study, by a team  including controversial Harvard astronomer Avi Loeb, suggests that the James Webb space telescope can be configure to spot evidence of LED light.

A surprisingly small population could save our species. A person walking in the Mojave Desert during the post-apocalyptic Wasteland Weekend festival on Sept. 28, 2019. (Image credit: Agustin Paullier/Contributor via Getty Images) From all-out nuclear war to a giant asteroid strike, its not hard to imagine ways human life on Earth could abruptly end. But assuming there are some survivors, how many people would it take to keep our species going?   The short answer is, it depends. Different cat...

Globular clusters are the oldest visible objects in the Universe – each contains hundreds of thousands to occasionally over one million stars, all born at essentially the same time. They are densely packed into a spherical volume with a diameter over a thousand times smaller than the diameter of the Milky Way Galaxy. Globular clusters are thought to have formed soon after the Universe began nearly 13.8 billion years ago, at the same time as, or perhaps even before, the first galaxies formed. ...

“Flares occur when magnetic field lines in the star twist and snap, releasing radiation and accelerating electrons and charged particles outwards,” MacGregor told SYFY WIRE. “The properties of the millimeter emission indicated that it was directly tracing those accelerated electrons. Because millimeter and UV emissions traced each other so closely, it might mean that millimeter observations could tell us about the limits of the UV environment of stars and exoplanets."  Though Proxima Ce...

galaxymap.org A cosmic census of the currently known objects in the vicinity of our sun has revealed that there are 540 stars and planets in the immediate neighbourhood. Using existing databases of objects alongside data from the European Space Agency’s Gaia telescope, which is mapping billions of stars in our galaxy, Céline Reylé at the UTINAM Institute in France and her colleagues pooled all knowledge of objects within 10 parsecs, or 33 light years, of our sun.

Massive Flare Seen Close to Our Solar System: What It Means for Chances of Alien Neighbors 2,887 The sun isn’t the only star to produce stellar flares. On April 21, 2021, a team of astronomers published new research describing the brightest flare ever measured from Proxima Centauri in ultraviolet light. To learn about this extraordinary event, and what it might mean for any life on the planets orbiting Earth’s closest neighboring star, The Conversation spoke with Parke Loyd, an astrophysic...

May 4, 2021 In May 2019, astronomers measured the largest flare ever from Proxima Centauri, the closest star to our sun. What do such flares mean for possible alien life, on a planet in the Proxima Centauri system, only 4 light-years away? Proxima Centauri is the closest star to the solar system and is home to a potentially habitable planet. Image via Hubble/ European Space Agency/ WikimediaCommons.
