Missing ingredient for life finally found on a comet

Researchers have detected phosphorus on a comet – thereby completing the grocery list of elements that are essential for life. The discovery was made in data from comet 67P/Churyumov-Gerasimenko by the Rosetta probe a few years ago, strengthening the i… Continue reading Missing ingredient for life finally found on a comet

Philae’s second touchdown gouged out a skull-like face on comet 67P

Scientists have discovered the second site at which ESA’s ill-fated Philae lander touched down on comet 67P/Churyumov-Gerasimenko, and in so doing revealed that the ancient ice hidden under the surface of the comet is softer than the froth on a cappucc… Continue reading Philae’s second touchdown gouged out a skull-like face on comet 67P

Interstellar organic matter might be a major source of Earth’s water

Earth is a famously watery planet, but where exactly it all came from is a mystery. Now, researchers in Japan have suggested a new origin story, by showing that water – and petroleum – can form inside clouds of organic matter, at high temperatures and … Continue reading Interstellar organic matter might be a major source of Earth’s water

New theory proposes ‘Oumuamua is an interstellar hydrogen iceberg

The exact nature of the bizarre interstellar object ‘Oumuamua remains a mystery. There’s been no shortage of ideas, but now astronomers at Yale and the University of Chicago have proposed that it’s a brand new type of object: a hydrogen iceberg.Continu… Continue reading New theory proposes ‘Oumuamua is an interstellar hydrogen iceberg

ESA’S Solar Orbiter set for unexpected rendezvous with Comet ATLAS

The European Space Agency’s Solar Orbiter is set to have a chance encounter with the two tails of the disintegrating Comet ATLAS over the coming days. The spacecraft is currently en route to the inner solar system for a close pass with the Sun, and has… Continue reading ESA’S Solar Orbiter set for unexpected rendezvous with Comet ATLAS

ATLAS telescope spots an asteroid that has sprouted a comet-like tail

Scientists using the University of Hawaii‘s Asteroid Terrestrial-impact Last Alert System (ATLAS) telescope have discovered an asteroid that shows the property of a comet. Designated 2019 LD2, the Trojan asteroid shares the same orbit as Jupiter, yet e… Continue reading ATLAS telescope spots an asteroid that has sprouted a comet-like tail
