The newly discovered comet might be an interstellar visitor

If it is interstellar, it would be only the second such object detected.
This artist’s impression shows the planet K2-18b, it’s host star and an accompanying planet in this system. K2-18b is now the only super-Earth exoplanet known to host both water and temperatures that could support life. UCL researchers used archive data from 2016 and 2017 captured by the NASA/ESA Hubble Space Telescope and developed open-source algorithms to analyse the starlight filtered through K2-18b’s atmosphere. The results revealed the molecular signature of water vapour, also indicating the presence of hydrogen and helium in the planet’s atmosphere.

First Water Detected on Planet in the Habitable Zone

Scientists reproduced the dynamics behind high-energy astrophysical shocks

Now experiments led by researchers at the U.S. Department of Energy’s (DOE) Princeton Plasma Physics Laboratory (PPPL) in the Princeton Center for Heliophysics have for the first time reproduced the process behind the source of astrophysical shocks.

Meteors help Martian clouds form

Enormous cloud-like plumes reaching 260km above the surface of Mars have left scientists baffled. This is way beyond Mars’s typical weather, entering into the...

Moon formation brought water to the Earth

Earth is the only terrestrial planet with a large amount of water and a relatively large moon, which stabilizes the Earth's axis. Earth grew...

Explosions of universe’s first stars spewed powerful jets

After the Big Bang and before the first stars ignited, the universe was a very dark and cold place. There were no galaxies, no...
