Scientists have located the coldest brown dwarf star ever observed, an important "missing link" among these celestial bodies that are half-planet, half-star, according to a study released Thursday. picked by AutumnLotus 7 months ago

A class of "failed" star called a brown dwarf emits beams of radiation that are thousands of times brighter than any released by the Sun. picked by AutumnLotus 2 years ago

Astronomers using the Hubble Space Telescope and W. M. Keck Observatory have found a lopsided debris disk around a young star known as HD 15115. As seen from Earth, the edge-on disk resembles a needle sticking out from the star. picked by AutumnLotus 1 year ago

An unusual star may have swallowed its stellar companion and burped out a planet-forming cloud as a result, a new study reports. The star, called BP Piscium, is surrounded by a thick disc of gas and dust from which it appears to be sucking up new material at a prodigious rate. picked by AutumnLotus 9 months ago

Probing a glowing bubble of gas and dust encircling a dying star, NASA's Hubble Space Telescope reveals a wealth of previously unseen structures. The object, called NGC 2371, is a planetary nebula, the glowing remains of a Sun-like star. The remnant star visible at the center of NGC 2371 is the super-hot core of the former red giant, now stripped of its outer layers. picked by AutumnLotus 9 months ago

A rare new kind of star may have been discovered. It is much like the white dwarf our own sun should eventually become—save for a mysterious shroud of carbon ash. The findings could shed light on the life and death of stars, astronomers said. picked by AutumnLotus 12 months ago

A tiny star recently unleashed what is considered the brightest burst of light ever seen in the universe from a normal star. Shining with only 1 percent of the sun's light and boasting just a third of the sun's mass, this run-of-the-mill star previously was nothing to write home about. picked by AutumnLotus 6 months ago

By studying in great detail the 'ringing' of a planet-harbouring star, a team of astronomers using ESO's 3.6-m telescope have shown that it must have drifted away from the metal-rich Hyades cluster. This discovery has implications for theories of star and planet formation, and for the dynamics of our Milky Way. picked by AutumnLotus 7 months ago

For the first time, astronomers think that they've found evidence of an alien solar system around a star close enough to Earth to be visible to the naked eye. picked by AutumnLotus 3 weeks ago

A developing star wrapped in a black cocoon of dust is seen sprouting giant jets in a new image from NASA's Spitzer Space Telescope. The stellar portrait, captured in infrared light, offers the first glimpse at a very early stage in the life of an embryonic sun-like star - a time when the star's natal envelope is beginning to flatten and collapse, and streams of gas are escaping. picked by AutumnLotus 12 months ago

A massive exploding faraway star _ the brightest supernova astronomers have ever seen _ has scientists wondering whether a similar celestial fireworks show may light up the sky much closer to Earth sometime soon. picked by AutumnLotus 2 years ago

Stars in dwarf spheroidal galaxies behave in a way that suggests the galaxies are utterly dominated by dark matter. Mario Mateo and Matthew Walker measured the velocity of 6,804 stars in seven dwarf satellite galaxies of the Milky Way: Carina, Draco, Fornax, Leo I, Leo II, Sculptor and Sextans. They found that, contrary to what Newton's law of gravity predicts, stars in these galaxies do not move ... read full post picked by AutumnLotus 1 year ago

Using observations from ESO's VLT, astronomers were able for the first time to reconstruct the site of a flare on a solar-like star located 150 light years away. The study of this young star, nicknamed 'Speedy Mic' because of its fast rotation, will help scientists better understand the youth of our Sun. picked by AutumnLotus 11 months ago

Astronomers have sighted a very dense planet-sized object that orbits its parent star in just four days and six hours. picked by AutumnLotus 1 month ago

The two most massive stars ever discovered are circling each other 20,000 light years away near the centre of the Milky Way. The heavier of the two is 114 times as massive as the Sun – so big that according to some astronomers it should have blown itself to pieces. picked by DrNothing 1 year ago

Planets may be present in a quadruple star system 150 light years from Earth, according to Spitzer Space Telescope observations. The system, called HD 98800, consists of two pairs of stars in which the partners in each pair orbit one another closely. The pairs themselves travel around each other on a very elongated path. picked by AutumnLotus 1 year ago

Astronomers have observed for the first time a jet of matter spiraling outward from an infant star, as if a lengthy strand of curly pasta. The enormous jet, which shoots out in two directions, is rocketing material away from the so-called protostar and into interstellar space at more than "supersonic speeds." picked by AutumnLotus 11 months ago

The image from NASA's Chandra X-ray Observatory shows the first double-sided X-ray jet ever detected from a young star. A similar jet may have been launched from the young Sun and could have had a significant impact on the early solar system. picked by AutumnLotus 7 months ago

Some of the most massive stars might not explode as supernovae, a new study suggests. Rather, researchers speculate, they simply collapse into black holes or if they do generate explosions, they're not as intense as the deaths of less massive stars. picked by AutumnLotus 7 months ago
