Die US-Regierung plant drastische Kürzungen im #NASA-Wissenschaftsbudget – von 7,3 auf 3,9 Milliarden Dollar.

Betroffen wären zentrale Missionen wie die Probenentnahme auf dem Mars und das Nancy Grace Roman Space Telescope.

Lediglich #Hubble und #Webb sollen weiterhin finanziert werden. Fachleute bezeichnen die Vorschläge als tiefgreifend und warnen vor dem Verlust laufender und geplanter Projekte.

Hubble Space Telescope image of Arp 147, also known as IC 298.

The clumpy, blue ring in the galaxy on the right likely formed when the companion galaxy to the left crashed through its center. This sent a pressure wave outward, like a ripple in a pond, compressing the right galaxy's gas and triggering the formation of new stars.

Two ring-like galaxies. On the left is a galaxy with a bright core surrounded by a yellow ring. There is a gap between the core and ring where the black background of space shows through. The galaxy is tilted so that the circular ring appears oval-shaped. On the right is a another circular galaxy, made mostly of a ring of bright blue dots, which are star clusters. On the bottom left part of the ring is a haze of white stars and orangish dust. The center of the ring is empty and the black background of space shows through. This galaxy looks a little like the writing of the aliens from the movie Arrival.

Hubble legt een onbekende kleine planetaire nevel vast

Deze relatief onbekende planetaire nevel, met de officiële naam Kohoutek 4-55, bevindt zich in ons Melkwegstelsel.

Hubble image of Arp 283, also known as NGC 2798 and NGC 2799.

The left galaxy in this interacting pair, NGC 2799, is viewed edge-on. A bridge of star forming regions appears to connect it to its companion on the right, NGC 2798. NGC 2798 has two broad smooth spiral arms or tails without obvious clumps, made of mostly older, yellow stars.

A pair of interacting galaxies. The galaxy on the left is seen edge-on. It has a bright yellow central core and a slightly warped blue disk that is dotted with star clusters and clumps of dark dust. The edge of the disk arcs to the right, appearing to connect to its companion galaxy. The second galaxy is inclined, but seen closer to face-on. It has a central bar of blue-ish stars that is largely obscured by a haze of yellow stars and dust lanes in the circular core of the galaxy. Two spiral arms emerge from the core, which are wide, poorly defined, and mostly made of yellow older stars, which is unusual for a spiral galaxy.

Across the Universe - When it was a just-born
It seems yesterday (sob!)

Confirmed now to be 13.8 billion years (± 0.1%) before Internet, this kid is still growing-expanding since, at a confirmed rate of 67 - 68 km /second/megaparsec (± 3.26 million light years), i.e a galaxy at one megaparsec from Earth is receding from us at 67 to 68 kms/sec (± 241-245 000 km/h, just a little faster than my moped).
