Apollo samples provide evidence: Researchers analyzed Moon rocks brought back by the Apollo missions and, for the first time, ...
To our best of our understanding, the Moon formed from Earth following a colossal impact. A Mars-sized world we nicknamed ...
A groundbreaking study published in Communications Earth & Environment has called into question the long-standing assumptions about how our solar system came to be. Tiny shavings from a meteorite ...
About 4.5 billion years ago, the most momentous event in the history of Earth occurred: a huge celestial body called Theia ...
The newborn planetary system appears to be emerging 1,300 light-years away around a baby star known as HOPS-315. Planet-forming materials were first identified using NASA's James Webb Space Telescope.
About 4.5 billion years ago, a colossal impact between the young Earth and a mysterious planetary body called Theia changed everything—reshaping Earth, forming the Moon, and scattering clues across ...
Tiny historical events, like early collisions of rocks in the solar system, influenced Earth’s formation, tilt, and moon, ...
"The most convincing scenario is that most of the building blocks of Earth and Theia originated in the inner solar system. Earth and Theia are likely to have been neighbors." Over 4.5 billion years ...
New research suggests that Theia, the object whose collision with Earth is theorized to have caused the formation of the moon ...
Peering through a cosmic keyhole at distant baby star, astronomers may have opened a new window on the deep past of our own solar system. Weighing in at 0.6 solar mass, HOPS-315 should someday grow to ...
The workings of our solar system are roughly the same now as they have been for millions of years. Moons circle their planets, the planets circle the sun, the sun’s magnetic fields and sunspots wax ...
An image from the ALMA telescope array in Chile shows jets of silicon monoxide blowing away from the young star HOPS-315. The blue jet is moving towards Earth, and the red jet is moving away from us.
