By combining transit photometry, radial velocity observations, and asteroseismology, astronomers have gathered important information about the properties of a highly eccentric, eclipsing binary system known as KOI-3890. The ...
A new study published February 28 on arXiv.org suggests that a millisecond pulsar known as PSR J0740+6620 has a stellar companion. The research provides evidence indicating that this object is most likely accompanied by an ...
Astrophysicists have found the first ever evidence of gigantic remains being formed from repeated explosions on the surface of a dead star in the Andromeda Galaxy, 2.5 million light years from Earth. The remains or "super-remnant" ...

Many scientists believe the Earth was dry when it first formed, and that the building blocks for life on our planet—carbon, nitrogen and water—appeared only later as a result of collisions with other objects in our solar ...

(Phys.org)—Astronomers have spotted transient, transit-like dimming events of a young star named RIK-210 located some 472 light years away in the Upper Scorpius OB association. However, what puzzles the scientists is the ...
Searching the universe for strange new star systems can lead to some pretty interesting finds. And sometimes, it can turn up phenomena that contradict everything we think we know about the formation and evolution of stars. ...
