Astronomers capture radio signal from distant galaxy
How do stars form in distant galaxies?
Astronomers have long been trying to answer this question by detecting radio signals emitted by nearby galaxies.
However, these...
This small laser device can help detect signs of life on other planets
As space missions delve deeper into the outer solar system, the need for more compact, resource-conserving and accurate analytical tools has become increasingly critical—especially...
Active galactic nuclei are even more powerful than thought, shows study
Powered by supermassive black holes swallowing matter in the centers of galaxies, active galactic nuclei are the most powerful compact steady sources of energy...
How do rocky planets really form?
Scientists unveil a unified theory for rocky planet formation.
New study reveals a star’s unexpected survival
As the star is shredded, its remnants are transformed into a stream of debris that rains back down onto the black hole to form a very hot, very bright disk of material swirling around the black hole, called an accretion disc.
Why new exoplanet discovery is a big deal
Researchers have discovered an Earth-sized exoplanet—a planet outside of our solar system.
The planet, named TOI-700 e, falls within its star’s habitable zone, meaning it...
Scientists find closest and oldest ultracool dwarf binary ever observed
Northwestern University and UC San Diego astrophysicists have discovered the tightest ultracool dwarf binary system ever observed.
The two stars are so close that it...
Astronomers discover the closest black hole to Earth
Astronomers have discovered the closest black hole to Earth, the first unambiguous detection of a dormant stellar-mass black hole in the Milky Way.
Its close...
Astronomers find the most distant stars in our galaxy halfway to Andromeda
Astronomers have discovered more than 200 distant variable stars known as RR Lyrae stars in the Milky Way’s stellar halo.
The most distant of these...
Scientists discover system’s second earth-size planet
Scientists have identified an Earth-size world, called TOI 700 e, orbiting within the habitable zone of its star – the range of distances where liquid water could occur on a planet’s surface.
