The Horsehead #Nebula

The Horsehead Nebula, part of the Orion complex 1,500 light-years away, is a cloud shaped by stellar forces. Cataloged as Barnard 33 and visible against the IC 434 emission nebula, it houses forming stars. Though visible with small telescopes, its shape will change over millions of years.

PEINLICHSTE
PERSÖNLICHKEIT

[ Jede:r von Euch darf die 3 Worte benutzen,
wenn Ihr dazu das Foto von jemanden richtig,
richtig peinlichen anhängt ]

Ich fang mal an:
William H. Macy in der Rolle des Jerry Lundegaard in "Fargo"
- schauspielerisch eine geniale Leistung!

💬 Diskutieren, während die Welt untergeht.

24 Tage, 24 Songs fürs Klima.

🎶 “Musik und Aktivismus kann man nicht trennen” sagte der deutsch-französische Künstler Mal Élevé in einem Interview, und setzt das in seiner Musik auch konsequent um. Mit Rap, ein bisschen Reggae und einem Hauch World Music und deutsch-französischen Texten beschwört er uns in „Planet“, endlich zu verstehen, dass wir nur diesen einen Planeten haben.▶️ Hier geht's zum Song: https://www.youtube.com/watch?v=v0prZXF-tzI

The Heart of the Soul #Nebula

A telescopic view of the Soul Nebula's IC 1871, this image shows dark dust clouds and glowing gas about 25 light-years across. Part of a larger complex 6,500 light-years away in Cassiopeia, it illustrates triggered star formation sculpted by young stars' winds and radiation.

#KnowledgeBit: A #Carbon #Planet is a theoretical type of planet that contains more carbon than oxygen.

In 2020, survey of the 249 nearby solar analog stars found 12% of stars have C/O ratios above 0.65, making them candidates for the carbon-rich planetary systems.

Of the seven Earth-sized worlds orbiting the red dwarf #star TRAPPIST-1, one #planet in particular has attracted the attention of scientists, because it orbits the star within the distance where water on its surface is theoretically possible – but only if the planet has an #atmosphere.

The basic thesis for TRAPPIST-1e is this: If it has an atmosphere, it’s #habitable.

Now, based on an examination of four of the planet's transits with transmission spectroscopy, astronomers have identified weak fingerprints of #methane.

But this does not necessarily imply the planet has an atmosphere and is habitable because it is not certain whether the methane is attributable to molecules in the atmosphere of the planet or in the host #star.

Or perhaps the tentative detection is not true at all.
