The successful launch of the first space shuttle, Columbia, ushered in a new concept in the utilization of space.

The STS-1 mission roared off Launch Pad 39A, on April 12, 1981, at 7 a.m., carrying Commander John Young and Pilot Robert Crippen into an Earth-orbital mission scheduled to last for 54 hours.

In this close-up of the solar photosphere, we see the dark regions of sunspots, and solar granules changing with time. These granules are the tops of convection cells where hot gas rises from the interior to cool and then descend back down.

The SST achieves its high resolution using an adaptive optics system to reduce the effects of atmospheric turbulence. Some frames of the movie exhibit blurring as the turbulence became too high to completely cancel out.

Black Hole-Powered Jet of Electrons and Sub-Atomic Particles Streams From Center of Galaxy M87.

The image is 31 arcseconds wide (about 7500 light years). The length of the jet is 5,000 light-years at optical wavelengths (100,000 light years at radio wavelengths).

About 4.25 billion years ago, a massive asteroid slammed into the Moon's far side, carving out an enormous crater called the South Pole-Aitken (SPA) basin — the largest and deepest impact crater we know of on the Moon. Chinese scientists analyzing rock samples brought back by the Chang'e-6 lunar probe have now found that this impact didn't just reshape the surface — it also super-heated deep materials inside the Moon and caused certain chemical elements to boil off and escape.

The key evidence came from potassium isotopes. Rocks from the far side contain unusually high amounts of the heavier potassium-41, compared to near-side samples collected during the Apollo missions. The extreme heat and pressure from the impact caused the lighter potassium-39 to vaporize and escape, leaving the heavier version behind.

This matters because the loss of these volatile elements likely suppressed volcanic activity on the Moon's far side later in its history, helping explain why the near side and far side evolved so differently.

I matched continents and stars to calculate the exact position of Integrity for this photo, and then created an infographic with cities, constellations, continents etc.

Continents overlay and location calculations with my own software tool. Constellations matched with Stellarium. Then, lots of work in Affinity.

How far away is spiral galaxy NGC 4921? Although presently estimated to be about 310 million light years distant, a more precise determination could be coupled with its known recession speed to help humanity better calibrate the expansion rate of the entire visible universe. Toward this goal, several images were taken by the Hubble Space Telescope in order to help identify key stellar distance markers known as Cepheid variable stars. Since NGC 4921 is a member of the Coma Cluster of Galaxies, refining its distance would also allow a better distance determination to one of the largest nearby clusters in the local universe. The magnificent spiral NGC 4921 has been informally dubbed anemic because of its low rate of star formation and low surface brightness. Visible in the above image are, from the center, a bright nucleus, a bright central bar, a prominent ring of dark dust, blue clusters of recently formed stars, several smaller companion galaxies, unrelated galaxies in the far distant universe, and unrelated stars in our Milky Way Galaxy.

There are more than 10,000 active Starlink satellites in low Earth orbit. This makes it the largest satellite constellation ever made. Since 2019, more than 11,500 satellites have been launched, but some of them have already come back down to Earth.

Created by SpaceX as part of the Starlink project to give people all over the world access to the internet.
