NASA hat zwei Optionen für Bodenproben vom Mars, Entscheidung soll 2026 fallen

Die vom Mars-Rover Perseverance gesammelten Bodenproben sollen auf der Erde wissenschaftlich untersucht werden. Die kostspielige Rückholmission bleibt offen.

Explanation:
What happens after a star explodes? A huge fireball of hot gas shoots out in all directions. When this gas slams into the existing interstellar medium, it heats up so much it glows. Two different supernova remnants (SNRs) are visible in the featured image, taken at the Oukaïmeden Observatory in Morocco. The blue soccer ball-looking nebula toward the upper left is SNR G179.0+02.6, which appears to be the smaller one. This supernova, about 11,000 light years distant, detonated about 50,000 years ago. Although composed mostly of hydrogen gas, the blue light is emitted by a trace amount of oxygen. The seemingly larger SNR, dominating the lower right of the frame, is the Spaghetti Nebula, cataloged as Simeis 147 and sh2-240. This supernova, only about 3,000 light years away, exploded about 40,000 years ago. …

2025 January 8 A star field appears that has several nebulas. Toward the upper left is a angularly small supernova remnant colored blue, while dominating the lower right is a large supernova remnant in both red and blue.

This supernova, only about 3,000 light years away, exploded about 40,000 years ago. Comparatively, even though they appear different sizes, both supernova remnants are not only roughly the same age, but about the same size, too.

"I think the success of a book, or whether it's saying to the reader what you want it to say, lies in the question of whether the thing that was in my heart when I wrote it might be in some way deposited into the reader's heart when they read it."

"...to be reminded of the earth's weird loveliness, but also see it as something that's quite robust. It's us who are in trouble -- the Earth will be fine. It's not the Earth we need to save, it's ourselves and all the other creatures on it."
