In 2017, a mysterious comet dubbed 'Oumuamua fired the imaginations of scientists and the public alike. It was the first known visitor from outside our solar system, it had no bright coma or dust tail, like most comets, and ...
Today Venus has a dry, oxygen-poor atmosphere. But recent studies have proposed that the early planet may have had liquid water and reflective clouds that could have sustained habitable conditions. Researchers at the University ...
With simulations that go into finer details than ever before, Brooke Polak of the University of Heidelberg and Hubert Klahr at the Max Planck Institute for Astronomy (MPIA) have modeled a key phase in the formation of planets ...
A comet is streaking back our way after 50,000 years.
A newly discovered comet could be visible to the naked eye as it shoots past Earth and the Sun in the coming weeks for the first time in 50,000 years, astronomers have said.
Here's a thorny problem: What if life doesn't always appear on planets that can support it? What if we find more and more exoplanets and determine that some of them are habitable? What if we also determine that life hasn't ...
The origin of Earth's water has been an enduring mystery. There are different hypotheses and theories explaining how the water got here, and lots of evidence supporting them.
ESA and OHB have signed a contract to move forward with the design and construction of ESA's ambitious Comet Interceptor spacecraft, planned for launch in 2029.
Researchers from Western have shown that a fireball that originated at the edge of the solar system was likely made of rock, not ice, challenging long-held beliefs about how the solar system was formed.
A new study from the University of Central Florida has found strong support that the outgassing of molecules from comets could be the result of the composition from the beginning of our solar system.
