This stunning image of a part of NGC 3372 emission #nebula in Carina was done by @AstroSabadell member Josep M Drudis.
This nebula is situated 7500 lightyears far and contains some of the most massive and bright stars of our galaxy and galaxy satellites.

After a supernova explosion the gas ejected may form a nebula called "supernova remnant" and could be one of the objects most beautiful in the heavens.

Distances in the Space are inmense: we see how galaxies were million years ago:

M33: its light from 2.7M years ago by A.Roig

M81: Light from 12M years ago, before any hominin lived on earth by J.Zapata

Quasar 3C279, as it was 5000M years ago, before earth was formed by X.Bros

What will find the Webb Space Telescope in TRAPPIST-1 system?
NASA will explain us LIVE on @TwitterSpaces on Feb 22nd, 2pm ET (19:00 UTC).
I expect a pre-Marketing campaign about what JWST could find (atmosphere detection) if JWST will work. Probably, one of its first targets!

One year ago chinese astronomers found 591 high-velocity stars from data of LAMOST & Gaia telescopes. They are situated in our galaxy halo and 43 of them can escape from the MilkyWay!
Runaway stars are a focus of research today:

Please, nobody has to forget the climate change threat: it's a dangerous risk we must try to solve as soogren as possible. It's an urgent duty for all.

The Horsehead Nebula (Barnard 33) is a small dark nebula in the constellation of Orion in a dense dust cloud known as Lynds 1630. It is 1375 lightyears far and it’s very popular because its shape: seems a horse head!!

In recent years have been identified stars in the Milky Way halo moving faster than the local escape speed. The origin of these hypervelocity stars is poorly understood and will be one area of study next years: https://t.co/pNEPVokayj

Four wonderful images of Comet Leonard. What will happen next weeks? A naked eye object? A binoculars one?… or just a telescope object? It is approaching us!!

The Helix planetary nebula is one of the nearest: “only” 700 lightyears distant.
The central old #star is losing its external layers creating the nebula.
Our sun will create also a planetary #nebula… in 4 or 5 billion years.
