One of the slowest CME (“solar storm”) releases I've seen – it's been going on for two days now and is still ongoing

Some experiment with Hubble program 17843. De-rotation to the next best full rotation with WinJUPOS and then slight alignment of the GRS. archive.stsci.edu/proposal_sea... Filter: F631N, only 3 frames, one frame with brightness adjusted, played time forwards and backwards.

The universe is likely filled with Mars-size planets, more so than Venus and super-Earth size planets. So what does Mars teach us about the evolution of planetary habitability, and the detection prospects for its exoplanet cousins? arxiv.org/abs/2605.18949

But wait! A new neural-net analysis of faint stars observed by TESS just identified another 10,090 potential planets! When they're confirmed (and most of them probably will be), they will more than double the number of known worlds beyond Earth. 🔭🧪 eos.org/research-and...

Every blue dot here is a star with known planets. Every orange dot, one with suspected planets. Nearly 6,000 total. Dot by dot, NASA’s TESS mission is filling in our picture of the Milky Way's strange new worlds. 🧪🔭 science.nasa.gov/missions/tes...

The building-sized asteroid will reach +11th magnitude at closest approach. Astronomer Gianluca Masi will feature the asteroid pass live tomorrow starting at 19:45 UT: www.virtualtelescope.eu/2026/05/12/n... - Will work out more sighting ops for this one this afternoon.

Tomorrow: 15-34-metre asteroid 2026 JH2 will pass ~91,000 kilometers (56,500 mi) from the Earth at 21:57 Universal Time (UT)/5:57 PM EDT. This is about a quarter of the Earth-Moon distance, and just over twice as far as geosynchronous orbit. Here's a capture of the inbound space rock from the 16th:
