Kosmos nie jest takim pustkowiem, za jakie się go uważa. No, prawie. W przestrzeni międzygwiezdnej, oprócz wszechobecnej próżni, unosi się niczym cieniutki welon gaz wodorowo-helowy oraz pył kosmiczny. To z nich składają się najpiękniejsze obiekty, które możemy oglądać na nocnym niebie – mgławice. Jedną z najbardziej spektakularnych mgławic widocznych na naszym niebie jest M16, zwana też Mgławicą Orzeł. #pieknonauki#hubble

Na zdjęciu widać słynne „Filarów Stworzenia” w Mgławicy Orzeł: wysokie, postrzępione kolumny ciemnego gazu i pyłu unoszące się w turkusowo-niebieskiej mgławicy, usiane drobnymi, złotymi gwiazdami.
💥 ASTEROID COLLISION IN ANOTHER SOLAR SYSTEM 💥
That famous “planet” near the bright star Fomalhaut? Not a planet. New Hubble data shows it — and a second object — are expanding debris clouds from massive asteroid collisions. Astronomers now think these smashups are far more common than models predicted. Space is rough out there.
Composite image of the 2012, 2013, and 2023 observations. The white light STIS images from three epochs have been averaged to show the relative positions of cs1 and cs2 (white labels) a decade apart. Fom cs1 appears as a linear radial feature because its position moved between 2012 and 2013. The data have been smoothed with a 0.8 pixel Gaussian filter. The dust belt is brighter to the east (left) because the dust grains have an asymmetric scattering phase function.
From source in toot: A pale blue dwarf galaxy seen on the black backdrop of space with some faraway galaxies. The galaxy itself resembles a fuzzy cloud of tightly-packed stars, with a broad halo of stars dispersed around it. Several small, glowing patches of gas are spread across the galaxy’s core, where very hot stars are concentrated.]
Two spiral galaxies fill the frame. The galaxy to the right is large and faint. It has a central bar and a loose, patchy ring of purple and blue star clusters. The left galaxy is smaller and brighter. It has two well-defined spiral arms, which spiral clockwise from a bright central point. The arms are dotted with bright white star clusters and outlined by dark dust lanes. The outer arms feature a less well defined haze of stars.
NASA’s Hubble Space Telescope has zoomed in on a stormy and highly active spiral galaxy named NGC 1792, providing a deeper view of the tumultuous activity taking place over 50 million light-years away. Read more from @nasa.gov:
This image, captured by the Hubble Space Telescope , shows the globular star cluster Omega Centauri which is located about 15,790 light-years from Earth.
Comet 3I/ATLAS is currently barreling its way through our solar system. Lucky for us, NASA’s Hubble Space Telescope has snapped the most detailed images of the comet yet. @LiveScience has more:
Der Blick zu den Sternen verbindet uns alle. Ins Universum schauen wir mittlerweile durch die #ISS, das #Hubble- und auch das James-Webb-Weltraumteleskop. Das sind Meilensteine auf unserem Weg in die Zukunft – als Menschheit. Unsere Technologie basiert auf Wissenschaft und vorurteilsfreier, internationaler Zusammenarbeit.
As soon as the end of February, NASA and the Jet Propulsion Laboratory will launch a new telescope into orbit around the Earth called SPHEREx. The funnel-shaped telescope weighs about as much as a grand piano and has a larger field of vision than other telescopes like Hubble and the JWST. @npr has more:
