Formation of the moon brought water to earth
Formation of the moon brought water to earth
The Earth is unique in our solar system: It is the only terrestrial planet with a large amount of water and a relatively large moon, which stabilizes the Earth's axis. Both were essential for Earth to develop life. Planetologists at the University of Münster have now been able to show, for the first time, that water came to Earth with the formation of the Moon some 4.4 billion years ago.

EUMETSAT, Japanese space agency to cooperate on greenhouse gas monitoring
EUMETSAT and the Japan Aerospace Exploration Agency (JAXA) today signed an agreement which will result in the agencies working closely together to monitor greenhouse gases in the Earth's atmosphere. Mr Kazuo Tachi, on behalf of the Direc tor General of JAXA's Space Technology Directorate 1 Ryoichi Imai, and EUMETSAT Director-General Alain Ratier signed the agreement at a ceremony at EUMETSAT's Darmstadt headquarters today.

Astroparticle physicists observe the longest half-life ever directly measured
Astroparticle physicists observe the longest half-life ever directly measured
The universe is almost 14 billion years old. An inconceivable length of time by human standards - yet compared to some physical processes, it is but a moment. There are radioactive nuclei that decay on much longer time scales. An international team of scientists has now directly measured the rarest decay process ever recorded in a detector.

Are Brown Dwarfs Failed Stars Or Super-Planets?
Are Brown Dwarfs Failed Stars Or Super-Planets?
Brown dwarfs fill the 'gap' between stars and the numerous smaller planets ' two very different types of astronomical objects. But how they originate has yet to be fully explained. Astronomers from Heidelberg University may now be able to answer that question. They discovered that the star Îoe Ophiuchi in the Milky Way is being orbited by two brown dwarfs, which in all probability formed along with the star from a gas and dust disk, just as planets do.

Cassini mission reveals the secrets of Saturn’s walnut-shaped ring moons
New study in in the high-ranking journal Science No 73/2019 from Mar 29, 2019 A new study of Saturn's small inner moons was published in the high-ranking journal Science . Images of Pan, Daphnis, Atlas, Pandora and Epimetheus, obtained by the Cassini spacecraft in winter 2016/17, show that several of these so-called "shepherd moons" exhibit huge ridges around their equators, giving them a very peculiar and impressing walnut-like shape (Fig.

Tidal Tails - The Beginning Of The End Of An Open Star Cluster
Tidal Tails - The Beginning Of The End Of An Open Star Cluster
In the course of their life, open star clusters continuously lose stars to their surroundings. The resulting swath of tidal tails provides a glimpse into the evolution and dissolution of a star cluster. Thus far only tidal tails of massive globular clusters and dwarf galaxies have been discovered in the Milky Way system.
