Any life identified on planets orbiting white dwarf stars almost certainly evolved after the star's death, says a new study led by the University of Warwick that reveals the consequences of the intense and furious stellar ...
A 4.6-billion-year-old meteorite found in the laying in the imprint of a horseshoe is likely a remnant of cosmic debris left over from the birth of the solar system and could answer questions about how life began on Earth.
In the 1970s four spacecraft began their one-way trips out of our Solar System. As the first human-built objects to ever venture into interstellar space, NASA chose to place plaques on Pioneer 10 and 11 and golden records ...
Planetary scientists estimate that each year, about 500 meteorites survive the fiery trip through Earth's atmosphere and fall to our planet's surface. Most are quite small, and less than 2% of them are ever recovered. While ...
Earth is perfectly suited for organic life. It stands to reason then that similar worlds orbiting distant stars might also be rich with life. But proving it will be a challenge. One of the better ways to discover extraterrestrial ...
The widely studied metallic asteroid known as 16 Psyche was long thought to be the exposed iron core of a small planet that failed to form during the earliest days of the solar system. But new University of Arizona-led research ...
For the first time, a unique study conducted at Lund University in Sweden has tracked the meteorite flux to Earth over the past 500 million years. Contrary to current theories, researchers have determined that major collisions ...
A team of Leiden astronomers has managed to calculate the first 100 million years of the history of the Oort cloud in its entirety. Until now, only parts of the history had been studied separately. The cloud, with roughly ...
White dwarfs, the glowing cores of dead stars, often host disks of dusty debris. However, these debris disks only appear 10 to 20 millions of years following the star's violent Red Giant phase. A new paper by Planetary Science ...
If asked where meteorites come from, you might reply "from comets." But according to our new research, which tracked hundreds of fireballs on their journey through the Australian skies, you would be wrong.
