The European Space Agency last year signed a deal worth 129 million euros ($156 million) to build a spacecraft for a joint project with NASA examining how to deflect an asteroid heading for Earth.

In a NASA simulation of an asteroid impact, scientists concluded they couldn’t stop a space rock from decimating Europe

The experts fell short. The group determined that none of Earth’s existing technologies could stop the asteroid from striking given the six-month time frame of the simulation. In this alternate reality, the asteroid crashed into eastern Europe.
Meteorite study suggests Earth may have always been wet
(27.08.2020)
A new study finds that Earth’s water may have come from materials that were present in the inner solar system at the time the planet formed — instead of far-reaching comets or asteroids delivering such water.
Earth’s water may have been inherited from material similar to enstatite chondrite meteorites
(28.08.2020)
The origin of Earth’s water remains unknown. Enstatite chondrite (EC) meteorites have similar isotopic composition to terrestrial rocks and thus may be representative of the material that formed Earth. ECs are presumed to be devoid of water because they formed in the inner Solar System. Earth’s water is therefore generally attributed to the late addition of a small fraction of hydrated materials, such as carbonaceous chondrite meteorites, which originated in the outer Solar System where water was more abundant. We show that EC meteorites contain sufficient hydrogen to have delivered to Earth at least three times the mass of water in its oceans.
Nächte voller Sternschnuppen
Eine beeindruckende kosmische Lichtshow, der Lyriden-Meteorschauer, erreicht diese Woche rund um den 22. April ihren Höhepunkt. Die Wetteraussichten sind vielversprechend.
Superconductivity Has Been Discovered in Meteorites For The First Time
Scientists have found naturally occurring superconducting materials in extraterrestrial objects for the first time, discovering superconductive grains embedded inside two distinct meteorites that crash-landed on Earth.
Himmelsgucker erwartet Sternschnuppen-Spektakel
Bis zu 120 Sternschnuppen pro Stunde
Ihren Höhepunkt erreichen die Geminiden am Samstag: Bis zu 120 Sternschnuppen pro Stunde prognostiziert die Vereinigung der Sternfreunde.
Leonids Meteor Shower Peak
Watch the Leonid Meteor Shower peak live from Mathias West Virginia Saturday 11/16/2019 starting at 8PM Eastern time. We are expecting 10-15 meteors per hour. Thanks to Ed Abel for hosting the stream.
Leonids Meteor Shower 2019 – Leoniden Meteorstrom
Look to the sky: Two meteor showers expected to peak this week
According to the American Meteor Society, the Draconids will peak Tuesday night into Wednesday morning and the South Taurid meteor shower will peak Wednesday night into Thursday morning.
Sternschnuppen aus dem Stier für Frühaufsteher
Immer am 9. oder 10. Oktober kreuzt die Erde den Sternschnuppen-Schwarm der Südlichen Tauriden. Ursprung dieses Meteor-Regens ist vermutlich ein zerborstener Komet. Und deswegen haben die Tauriden wunderschöne Leuchtkugeln im Gepäck.
How to Watch the Peak of the Perseid Meteor Shower Tonight
One of the year’s best meteor showers peaks tonight into tomorrow and Wednesday, which means it’s a great opportunity to wake up early, find a dark place outdoors, and enjoy the spectacle.
Der Weltraum als „Zukunftsmarkt“
Wie der Verband erklärt, sei nicht nur die deutsche Wirtschaft auf eine eigenständige weltraumgestützte Satellitenkommunikation angewiesen, um sich „strategische Autonomie“ zu sichern; dies gelte auch für staatliche Stellen und vor allem für das Militär. Schließlich seien Einsätze der Bundeswehr „ohne Weltraumsysteme nicht mehr vorstellbar“.
The Small Comet 46P/Wirtanen Flies Close By Earth Next Month! Here’s What to Expect.
As you read this, a small comet is on its way toward making a very close pass of Earth in mid-December — its best appearance over a period of four centuries.
Prepare for Meteors, Comets, Stellar Nights in December
Meteor showers, comets, and planets will dance across December skies and stargazers will want to be prepared, astronomists say.
Riesiger Asteroid ist mit freiem Auge erkennbar
Noch bis 16. Juli hat man die Chance, auch ohne technische Hilfsmittel den Asteroiden am Nachthimmel zu erblicken, sowohl auf der Nord- als auch auf der Südhalbkugel. Danach entfernt er sich wieder zu weit, um ihn mit freiem Auge zu sehen.
@NASANewHorizons: All between that, @ExpanseSYFY and 17 years of worldwide war on error (at present just on this small planet), could you guys stop that subliminal „Weltraum macht frei“ messages and think for a second next time before you name a space object? Thanks a lot @NASA.
@NASANewHorizons: Q: has any other object ever gotten an „official nickname“ before getting it’s official IAU designation?
(13.3.2018)
@NASANewHorizons: I would have chosen „Grabthar’s hammer“.
(13.3.2018)
Our next flyby object, 2014 MU69, has a new nickname! The Kuiper Belt object will be known as “Ultima Thule!”
