Messier 81
apod.nasa.gov/apod/image/2503/…
One of the brightest galaxies in planet Earth's sky is similar in size to our Milky Way Galaxy: big, beautiful Messier 81. Also known as NGC 3031 or Bode's galaxy for its 18th century discoverer, this grand spiral can be found toward the northern constellation of Ursa Major, the Great Bear. The sharp, detailed telescopic view reveals M81's bright yellow nucleus, blue spiral arms, pinkish starforming regions, and sweeping cosmic dust lanes. But some dust lanes actually run through the galactic disk (left of center), contrary to other prominent spiral features. The errant dust lanes may be the lingering result of a close encounter between M81 and the nearby galaxy M82 lurking outside of this frame. Scrutiny of variable stars in M81 has yielded a well-determined distance for an external galaxy -- 11.8 million light-years.

Ancient Ogunquit Beach on Mars
apod.nasa.gov/apod/image/2503/…
This was once a beach -- on ancient Mars. The featured 360-degree panorama, horizontally compressed, was taken in 2017 by the robotic Curiosity rover that explored the red planet. Named Ogunquit Beach after its terrestrial counterpart, evidence shows that at times long ago the area was underwater, while at other times it was at the edge of an ancient lake. The light peak in the central background is the top of Mount Sharp, the central feature in Gale Crater where Curiosity explored. Portions of the dark sands in the foreground were scooped up for analysis. The light colored bedrock is composed of sediment that likely settled at the bottom of the now-dried lakebed. The featured panorama (interactive version here) was created from over 100 images and seemingly signed by the rover on the lower left.

Fomalhaut, photo by Hubble Telescope.
This stunning image shows the star Fomalhaut and its protoplanetary disk, resembling a fiery eye in space. Fomalhaut is about twice the mass of the Sun and still has a disk of gas and dust, similar to what once surrounded our Sun before planets formed.

SuperCam Target on Ma'az
apod.nasa.gov/apod/image/2503/…
What's the sound of one laser zapping? There's no need to consult a Zen master to find out, just listen to the first acoustic recording of laser shots on Mars. On Mars Rover Perseverance mission sol 12 (March 2, 2021) the SuperCam instrument atop the rover's mast zapped a rock dubbed Ma'az 30 times from a range of about 3.1 meters. Its microphone recorded the soft staccato popping sounds of the rapid series of SuperCam laser zaps. Shockwaves created in the thin Martian atmosphere as bits of rock are vaporized by the laser shots make the popping sounds, sounds that offer clues to the physical structure of the target. This SuperCam close-up of the Ma'az target region is 6 centimeters (2.3 inches) across. Ma'az means Mars in the Navajo language.

Thor's Helmet
Thor not only has his own day (Thursday), but a helmet in the heavens. Popularly called Thor's Helmet, NGC 2359 is a hat-shaped cosmic cloud with wing-like appendages. Heroically sized even for a Norse god, Thor's Helmet is about 30 light-years across.

Venus and the Triply Ultraviolet Sun

Venus and the Triply Ultraviolet Sun
This was a very unusual type of solar eclipse. Typically, it is the Earth's Moon that eclipses the Sun. In 2012, though, the planet Venus took a turn. Like a solar eclipse by the Moon, the phase of Venus became a continually thinner crescent as Venus became increasingly better aligned with the Sun. Eventually the alignment became perfect and the phase of Venus dropped to zero.

1/ When we first joined #mastodon we posted an image of our Extremely Large Telescope, currently under construction in #Chile, and we loved the enthusiasm it generated! Today we share with you a stunning time-lapse of the construction during last year: youtube.com/watch?v=KRcVJf0ims…

Taken with the VLT Survey Telescope (VST) at our Paranal Observatory, this image shows galaxy NGC 3640 and the close, smaller galaxy NGC 3641, now in NGC 3640's path.
A team of astronomers used the VST to analyse their globular clusters –– dense spherical conglomerations of old stars. These usually contain some of the first stars created within a galaxy and can therefore act as fossil markers, revealing the galaxy’s history, even after merging events.
The results confirm that NGC 3640 has engulfed other galaxies before. Yet it also shows that the interaction between NGC 3640 and NGC 3641, while fast, is not happening close enough for NGC 3640 to pose a threat... for now.

A new night begins at ESO’s Paranal Observatory, and comet C/2024 G3 makes a grand entrance ☄️ 😎 With it, a swarm of satellites – a growing concern for the darkest skies in the world...
At ESO we have worked extensively not only to measure the impact of satellite constellations on optical and radio observations, but also to escalate this issue to the highest levels.
➡️ eso.org/public/about-eso/dark-…
Thanks to the joint effort of several countries and institutions, this problem is now discussed annually in the Scientific and Technical Subcommittee of the United Nations Committee on the Peaceful Uses of Outer Space.
