What if we had the ability to chase down interstellar objects passing through our solar system, like 'Oumuamua or Comet Borisov? Such a spacecraft would need to be ready to go at a moment's notice, ...

A pair of researchers has found possible evidence of an extrasolar object striking the Earth back in 2014. In their paper uploaded to the arXiv preprint server, Amir Siraj and Abraham Loeb describe ...

Astronomers have detected a possible planetary-mass object with a surprisingly powerful magnetic field some 20 light-years from Earth. It can help scientists better understand magnetic processes on ...

When interstellar object Oumuamua was discovered in 2017, it sent shock waves throughout astronomy. Oumuamua’s odd cigar-shape and its origins from another solar system were unlike anything ever seen ...

Three extrasolar comets have been discovered around the star Beta Pictoris, 63 light years away. Analysis of data from the current NASA mission TESS has revealed the objects for the first time using ...

Astronomers have “cracked” a very cold case with the dissection of light from the coldest known brown dwarf. In fact, the brown dwarf, named WISE 0855, is billed as the most frigid discrete world yet ...

Orbiting the Earth 353 miles above the ground, the Hubble Space Telescope silently pivots toward its new target. At the same time, flying 93 million miles away in interplanetary space, NASA’s Spitzer ...

A few faint pixels of red light may constitute the first picture ever taken of a planet outside the solar system. The near-infrared light comes from an object residing close to a brown dwarf 230 light ...

Astronomers have taken the first picture of a planet-like object orbiting a star outside our solar system. Planet hunters have long sought such a direct view but the object is so large that they ...

Since early July, telescopes around the world have been tracking just our third confirmed interstellar visitor, the comet 3I/ATLAS—3I, for third interstellar, and ATLAS (Asteroid Terrestrial-impact ...

In a groundbreaking observation, astronomers have detected the first ever radio signal from the interstellar comet 3I/ATLAS, an object originating from outside our solar system. This unusual signal ...
