There's a partial solar #eclipse tomorrow! The #Moon will slip between #Earth and the #Sun, casting its shadow over us 🌞🌕🌍

To get in the spirit, let’s take a (very) close peek at our cosmic neighbour, with its crater-covered surface. And, sadly, no cheese in sight 🧀 👀

This image was captured in early January through the Nasmyth A focus of the UT1 telescope at our Very Large Telescope (VLT) in #Chile

Wow – didn’t think I’d be in tears today, but this message sent home from Gaia as it was shut down forever today hits hard 😭

What you’re seeing is a map of the 106 CCD detectors that Gaia used to measure the positions of billions of stars in the Milky Way for the past 11 years 🛰️✨

They were turned off in a special sequence … 😕

Wow wee, wow wow! JWST just keeps raising more questions than it's answering--& that's a good thing! JWST discovered that the toddler galaxy, GS-z13-1--which existed just 330 million years after the Big Bang--had ionized the ancestral neutral hydrogen that surrounded it allowing its light to transverse the universe & reach JWST. According to present hypothesis, that's incredibly early for a galaxy to have done that. https://www.esa.int/Science_Exploration/Space_Science/Webb/Webb_sees_galaxy_mysteriously_clearing_fog_of_early_Universe

The lasers our Very Large Telescope (VLT) pierce the Milky Way… but what is that vertical glow just below? 🤔

That’s the zodiacal light: caused by dust grains in the Solar System, it's so faint that it’s only visible in the darkest skies, such as those of Chile’s Atacama Desert.

And the pristine night sky 🌌 in this region has always been intertwined with the culture and traditions of its indigenous people, discover how: https://www.eso.org/public/images/potw2511a/

Check out these pics to catch one last glimpse of Saturn's rings before they "disappear" from view for a while! 🪐 🤩

On 23 March, the Earth's orbit will cross the plane of the rings, making the majestic rings appear edge-on from our perspective. Since Saturn will be positioned very close to the Sun in the sky, it won’t be possible to observe it as the Earth crosses the plane. ⁠The rings will then become visible again in September this year.

Courtesy of ESO astronomer Abigail Frost, these images were captured in early January through the Nasmyth A focus of Unit Telescope 1 at our Very Large Telescope (VLT) in #Chile .

#astrodon #astronomy #memes
An astronomy themed version of the "What a week" meme. There's a horizontal trumped-shaped diagram showing the evolution of the universe. Starting from the Big Bang to the left, the trumped broadens as the universe expands, ending with present-day galaxies to the right. There's a text that says "What a few billion years, huh?", pointing towards the left part of the diagram when the earliest stars and galaxies formed, only a few hundred million years after the Big Bang. Another text, pointing to the same location, answers "Captain, it's only the epoch of reionization." Image by NASA, modified by efbrazil.

Planetary party portrait above Paranal!

In this image, taken in early February, the planets of the Solar System appear to parade one after the other above our Paranal Observatory in #Chile. Joining the party are the #Moon, the #MilkyWay, and a special guest: comet C/2024 G3 ☄️

A question we often get is whether the planets orbit the Sun in the same plane as the disc of the Milky Way. This image shows that's not the case: the plane of the Solar System –the ecliptic– is tilted about 60º relative to the Milky Way.

The image is a circular fisheye projection, with the horizon around the circular edge and the highest part of the sky at the centre of the circle. It shows eight telescope domes around the edge. The moon lights the telescopes and the desert from behind, creating a haze across, but above it the sky is pretty dark and full of stars. Our Milky Way galaxy –– an arc made dense by white points and hues of pink and purple –– crosses the image vertically. Several planets, which look like dots, appear aligned more or less horizontally across the sky. The image is marked with text for white points of interest, including the Milky Way, planets and comet C/2024 G3, which looks like the streak of a shooting star, blazing white.

Hot new #JWST image just dropped. (Literally hot; the temperature inside this object can reach upward of 25,000 degrees.)

Meet the planetary #nebula NGC 1514, aka the "Crystal Ball Nebula". It's about 1500 light years away from Earth in the direction of the constellation Taurus.

Planetary nebulae occur toward the end of the lives of #stars that have about the mass of the Sun. They shed their outer layers into space, leaving behind an Earth-sized star called a white dwarf. Its temperature can be up to about 100,000 degrees, so it emits a lot of ultraviolet and X-ray light. That light energizes the gas ejected during the earlier phase, lighting it up like a neon sign. (NGC 1514's white dwarf is the bright star at the center with the spikes, which are an artifact of the telescope's optics.)

This image is a composite of individual frames made through three colored filters by the Webb telescope's Mid-Infrared Instrument (MIRI). The image shows two concentric shells of material whose bright edges appear as circles. It's actually an hourglass-shaped structure seen an angle inclined to our line of sight toward NGC 1514.

A newly published study finds that these rings are different than the reddish material inside them. The light they emit comes from very tiny grains of carbon-rich material given off by the progenitor star very late in its life.

But why the ring shapes? It turns out that the progenitor star was actually two, only one of which endured this phase of high mass loss. Energetic "winds" given off by the stellar pair shaped the carbon grains as they were pushed away from the system.

(Processing of this image was done by Judy Schmidt: https://www.flickr.com/photos/geckzilla/54206737999)

A colorful planetary nebula appears on a dark background. The nebula is a range of colors from red to pink to orange to white and consists of an inner reddish region surrounded by two diffuse gray/white rings tilted at 45 degrees toward the lower right. A bright star appears in the center with six short diffraction spikes. Faint stars and galaxies are scattered across the background.

From the stairs to the stars! 🪜✨ Other than going to #space, the next best way to feel close to the stars is from the dark skies high up in #Chile’s Atacama Desert, where our Very Large Telescope(*) is located.

Those yellow beams are the VLT’s laser guide stars, shooting up from the telescope (to the right, but outside of the frame) into the sky. The laser beams create artificial stars high up in the atmosphere, which the telescope’s adaptive optics system uses to make the sharpest possible observations of the cosmos, from the ground.

At the centre of the image is the silhouette of a person standing on a tall viewing platform, at least 5 metres high and almost just as wide. It has a two-level staircase leading up to it. The dark foreground silhouette of stairs and platform contrasts with the night sky filled with stars, showing blue and green hues, and the cloudy, white Milky Way plane reaching across, diagonally. At the top right, two orange laser beams emerging from outside the frame seem to converge towards the galactic plane.

There are probably thousands of other people who have posted information and explainers and resources, but just in case some folks haven’t seen those, I’d like to post some #IntroToAstro recommendations and resources.

One of my first recommendations tends to be Stellarium (https://stellarium.org/). It’s free! It’s like having a planetarium on your computer! There’s a simpler web version!

New observations of 2024 YR4 conducted with ESO’s Very Large Telescope and facilities around the world have all but ruled out an impact of the #asteroid with our planet. The asteroid has been closely monitored in the past couple of months as its odds of impacting Earth in 2032 rose to around 3%, the highest impact probability ever reached for a sizable asteroid.

Proba-3 is a highly under-publicized new space mission.

Two spacecraft will fly in formation to create solar eclipses on demand. The same basic technology could eventually lead to huge, virtual space observatories & to telescopes that can bring other Earths into view.

https://www.esa.int/Enabling_Support/Space_Engineering_Technology/Proba_Missions/Proba-3_Technologies #science #space #astronomy #esa
ESA’s double-satellite Proba-3 mission will be flying where no previous member of the Proba minisatellite family has gone before – up to 60 000 km away, a seventh of the way to the Moon. Set for launch in 2024, the two satellites will be launched together into a highly elliptical orbit, ranging from 600 km up to a high point of 60 000 km. For six hours per 19.5 hour orbit, the pair will line up so that the Occulter spacecraft casts a shadow upon the Coronagraph spacecraft to open up the Sun's corona atmosphere for sustained observation.

Proba-3 Technologies

A broad range of novel technologies are essential to make Proba-3 a success. The mission’s formation flying system includes components in both satellites, with a Formation Flying Management system being in charge of scheduling and planning formation …

This 30 sec iPhone 15 wide-field image shows open clusters like M35, faint planets like Uranus, & clearly separates both M42 & M43 in the Orion Nebula ✨

And since it detects stars almost to 10th magnitude (yes, I checked 🙂), you can readily make out the Taurus-Auriga dark clouds as regions where stars are 'missing' 🌚

This was a challenging photo. I captured it about 7 years ago while driving from Salt Lake City up to southern Montana to be in a friend's wedding. When I started looking into the logistics of my arrival time, I realized there would be an opportunity to photograph the Milky Way somewhere under the dark skies of northern Utah or southern Idaho. Not wanting to stray too far off the highway, I looked for areas that might offer a unique foreground for the composition.

I soon realized that the highway alignment (northwest to southeast) would allow for a "highway to the stars" type of image, and started looking for an ideal overpass. This one caught my eye and I couldn't have been happier with the results. It took some time to capture, as it was necessary to get all of the Milky Way images without traffic on the highway, and then of course I needed to get a few images with light trails from the cars on the highway below.

I didn't have star tracker at the time, but other than that there are few things I would've changed considering the challenge and how it turned out!
