NASA alt text: Earthset captured through the Orion spacecraft window at 6:41 p.m. EDT, April 6, 2026, during the Artemis II crew’s flyby of the Moon. A muted blue Earth with bright white clouds sets behind the cratered lunar surface. The dark portion of Earth is experiencing nighttime. On Earth’s day side, swirling clouds are visible over the Australia and Oceania region. In the foreground, Ohm crater has terraced edges and a flat floor interrupted by central peaks. Central peaks form in complex craters when the lunar surface, liquefied on impact, splashes upwards during the crater’s formation.

Just gorgeous images to look at on the NASA Johnson Flickr this morning www.flickr.com/photos/nasa2...
An image of the entire Earth, with Northern Africa and the North Pole visible at the lower left. It looks like daytime but it is actually illuminated by moonlight. There’s a bright arc along the lower right where the sun is coming through from behind. There’s a bright dot on the lower right (Venus) and a glow (zodiacal light). A few stars can be seen in the dark beyond the Earth.
An image of the entire Earth, with Northern Africa and the North Pole visible at the lower left. It is dark with muted colors. There’s a very bright arc along the lower right where the sun is coming through from behind. There’s a small dot on the lower right (Venus). The background is dark with a few faint stars visible.
The whole-Earth-at-night photo from the #Artemis II mission was brighter than many expected. That was mostly due to camera settings; here’s another pic taken just before with diff settings. Digital photography is always subjective—even before processing! (HT @swapnakrishna.com @jasonc0.bsky.social)
Spectacular high-resolution image of our home planet viewed through the Orion Crew Module window by the Artemis II astronauts as they continue their journey to the Moon on Flight Day 2, 3 April 2026 (pic: NASA)
A full disc image of Earth, as seen from the Orion Crew Module. The planet is a pale blue, swirling with white clouds and glowing slightly lighter blue in place from reflected light. At lower left, a large brown landmass is Africa, with Spain and Portugal with twinkling lights where the planet curves. At top right, auroras glow in a thin green glow, just barely separated from the planet's surface. Earth is set against the black of space (pic: NASA/R.Wiseman)
😮 Awesome views from Day 2 of #Artemis II this morning.

Wishing a happy 60th birthday to astronomer Conny Aerts! Her studies of star oscillations have unveiled new vistas in modeling the internal rotations of stars, earning her the Francqui Prize in 2012 and the Kavli Prize in 2022!

Årets mandelgave! #astronomiskeanekdoter
This week (!) is the 30th anniversary of the announcement of 51 Pegasi b, the first exoplanet found orbiting a star like our Sun - since then, we've found over 6,000!
To celebrate, @alexwitze.bsky.social and @nature.com collected some astronomers' favourite planets:

My goto 2player game is Patchwork, but perhaps not that worldbuildy. For a coop dungeon crawler, one deck dungeon is nice. Otherwise both Flamecraft and Critter Kitchen work quite well for 2. For a bit heavier, 7wonder duels or duel for middleearth are quite nice

Happy #HobbitDay to all!
On 22 September: Bilbo and Frodo Baggins were born. As Ring-bearers, born 78 years apart, their birthdays were honoured as Cormarë, and Tolkien societies worldwide continue to commemorate. How will you celebrate? #Tolkien #BookSky
To mennesker nyder et glas vin under stjernerne, i silhuet. Stjernebilledet Cassiopeia er særligt fremhævet. Med hvid skrift står "Starhopping IDA Space Talks"
For tiden kan man på stjernehimlen se "Clash og the Titans" udfolde sig. Det har jeg talt med @nothansolo.bsky.social om i en @ida.dk - Space Talks podcast. 🔭 🇩🇰

OMG YOU GUYS OMGOMGOMG
I found evidence of the possibility that perhaps there’s a slight chance that there could feasibly be a plausible sign that there MAYYYYYY be life on Mars
Potentially
Super lavtflyvende over Lyngby. Det lignede et militært transportfly escorteret af to kampfly, så ja... Fancy politisk besøg?
The "Hair" reference. Chef's kiss
@brodersen.dk Something more for you to test and play with :p
My fiance gets allergic reactions from the hypoallergenic tape, but not from the regular band-aid tape. Are there no alternatives for you? It sounds absolutely dreadful.
Tillykke!
A black and white photograph of Henrietta Swan Leavitt. She is wearing a white blouse with a large lace collar that covers her shoulders, upper chest, and neck. Her hair is pulled up and she is looking directly at the camera. She has dark eyes in tis photo, strong eyebrows, and a long, thin nose.
Astronomer Henrietta Swan Leavitt was born #OTD in 1868. She established the period-luminosity relation for Cepheid variable stars, an essential tool for understanding the scale of our Universe. 🧪 👩🔬 🔭

The number of working satellites has soared in the past five years to around 11,000, mostly because of constellations of orbiters that provide Internet connectivity around the globe, but it comes with a series of problems. Nature explores the issues and how scientists are reacting. 🔭 🧪
Gaia spacecraft in space in front of the Milky Way galaxy
Today we say goodbye to ESA’s Milky Way-mapper Gaia! The Gaia spacecraft has completed its sky-scanning and will be switched off this morning.

White marble gravestone, with the text "Andreas Morgenrødt, Tidsrejsende 1996 - 2064"
This is kinda of a thing. This is a grave stone at the "Assistant" Cemitary in Copenhagen. The text say "Andreas Morgenrødt, Timetraveller 1996 - 2064" As far as i remember it was an art installation, installed illegaly one night and never removed because it's fun.
