Nice comparison of size of the sun vs the rest of the solar system and yet compared to the rest of the universe it’s nothing special. m.youtube.com/shorts/RSLkk...

How it started, how it's going Left: Lunar Orbiter I, 1966 Right: Artemis II, 2026 flic.kr/p/8Grtp2 flic.kr/p/2s68RXM #Artemis 🧪🔭

The world's first view of Earth taken by a spacecraft from the vicinity of the Moon. The photo was transmitted to Earth by the United States Lunar Orbiter I and received at the NASA tracking station at Robledo De Chavela near Madrid, Spain. This crescent of the Earth was photographed August 23, 1966 at 16:35 GMT when the spacecraft was on its 16th orbit and just about to pass behind the Moon. Credit: NASA.

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—formed when the surface rebounded upward during the impact that created the crater. Image Credit: NASA.

More context on this #Artemis II image: * This is the night side, lit by moonlight. You can see city lights in Spain & Portugal, & a sliver of day at lower right * The Sun is entirely behind Earth, which makes it a kind of solar eclipse, but w/ Earth doing the eclipsing instead of the Moon: ☀️🌍🚀🌕

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)

AFTER 25 YEARS, HUBBLE HAS LOOKED AT THE CRAB NEBULA AGAIN AND GIVEN US A BEAUTIFUL NEW LOOK!!

$Colorful nebula in space with a white haze throughout that is more concentrated in the center with a rippling effect. Colorful gas filaments appear to splash outward from the nebula center, colored yellow, magenta, and blue. A faint black border with right angles at the corners of the images show where the telescope\u2019s field of view stopsdotted line with right angles shows the borders of the telescope\u2019s image. Small white stars dot the background.$

Another comic I never bothered posting This one from 2023. Topical galileo humour apropos of precisely nothing at all

1. [Title Panel]: Is Your 17th Century Astronomer Spending Too Much Time on His Telescope?

2. [Text -only panel] These days, more and more 17th Century Astronomers have access to telescopes. Here are some warning signs that they are on the slippery slope to Godless heliocentrism!

3. STAYING UP LATE WITH THEIR TELESCOPE

[GALILEO is looking through his telescope out the window at a starry sky].

GALILEO'S WIFE:
Go to bed, Galileo!

GALILEO: In a minute...

4. ‘FOMO’ (FEAR OF MISSING OBSERVATIONS)

GALILEO'S WIFE:
Dinner, Galileo!

GALILEO [Looking through telescope]:
Just need to check my orbits

5. WITHDRAWING FROM REAL-WORLD ACTIVITIES

[Galileo's friend the POPE is now standing next to Galileo, who is still looking through his telescope]

THE POPE: Come to church, Galileo!

GALILEO: Not now...

6. FALLING OUT WITH FRIENDS

GALILEO: [Showing The Pope the book he's working on) I'm just working on my book challenging the Bible's view of the Universe

7. BEING ARRESTED BY THE INQUISITION

[GALILEO is being dragged out of the room, hands outstretched to his telescope. He is calling to it]:

GALILEO: Telescooope

9. GETTING SENTENCED TO HOUSE ARREST UNTIL DEATH FOR HERESY

[GALILEO sitting in front of his telescope, now with bars over the windows]

GALILEO: Ah, crap.

10. CONTINUED TELESCOPE USE DESPITE NEGATIVE CONSEQUENCES

[GALILEO in same position but now with long white beard, he is looking through his telescope through a barred jail window at the sky]

GALILEO'S WIFE:
Go to bed, Galileo!

GALILEO: In a minute...

[Ends]

1/n 2 NEW epic images of Phobos over Mars just released by @esa.int Mars Express This view is especially striking, with Phobos between the Tharsis volcanoes and Noctis Labyrinthus–Valles Marineris Full resolution 300MP(!) & info on: flic.kr/p/2rMW4so Credit: ESA/DLR/FUBerlin/AndreaLuck CC BY 🧪🔭

$A wide view of the planet Mars fills the frame, shown as a curved, rust-colored world against black space. The bottom edge fades into darkness, marking the planet’s night side, while the upper portion is brightly lit by sunlight. Near the right side are three large, round volcanic mountains of the Tharsis region, each with a wide circular base and a darker central caldera, resembling shallow craters pressed into the surface. North of these volcanoes, stretching almost vertically across the upper right half of the planet, lies Noctis Labyrinthus and Valles Marineris: an immense system of deep canyons and fractured terrain that appears as pale, branching scars and cracks, partly softened by hazy, cloud-like atmospheric features. Near the center of the image, positioned between the volcanoes and the canyon system, a small dark oval appears against Mars’s surface. This is Phobos, one of Mars’s satellites. Its tiny size stands out sharply against the vast scale of the planet below.$

The average impact velocity at the Moon is somewhere between 16 and 20 kilometres per second. This is the result of even a modest space rock hitting the lunar surface at that speed.

Recently had a conversation with a friend who doesn’t really follow the space biz and had no idea that we were on the cusp of launching a mission to send people back to the Moon. Gonna be a lot of surprised people in Feb/March. Even more so to learn this is a NASA thing, not a billionaire thing.

Light and gravity travel at the same speed, but don’t arrive together Yes, light waves and gravitational waves travel at exactly the same speed. But when cosmic events create both at the same time, they don't arrive together. Here's why. bigthink.com/starts-with-... #astro #space #gravity #light

bigthink.com

Light and gravity travel at the same speed, but don't arrive together

In 2017, a kilonova sent light and gravitational waves across the Universe. Here on Earth, there was a 1.7 second signal arrival delay. Why?
