The light beyond sight

Only a tiny sliver of the Universe’s light can be seen by human eyes. But today we’re catching glimpses of the invisible

William Herschel by Lemuel Francis Abbott c1785.

Herschel is shown seated or half-length, turned slightly to one side, with a calm yet intense gaze that suggests intellectual depth and curiosity. His expression is serious and reflective, as though engaged in thought or observation.

Attire: He wears formal 18th-century clothing, typically a dark coat and waistcoat with a white cravat.

The NLC season has started in Washington state!
I have a fascination with these rare, very high-altitude noctilucent or night shining clouds (NLC) hanging at the edge of space with an electric blue glow, can’t be mistaken when these beautiful luminous blue-white tendrils are spreading across the sky in sunset afterglow over the Salish Sea (as seen here).

They’re composed of very small water ice crystals formed on minute particles of dust, possibly of cosmic origin from micrometeors. They are visible in the northern hemisphere at latitudes between 45˚and 65˚north, and occur after sunset or before sunrise from mid June to the end of July here at our latitude (47°).

An amateur astronomer may have just spotted the first known comet (or asteroid) impact on Saturn.

We've seen impact flashes on the Moon & Jupiter, but this would be by far the most distant one yet observed. 🧪🔭

Mario Rana in Virginia captured this frame of Saturn at 5:07:56 a.m. EDT (9:07:56 UTC) on July 5, 2025. See that bright flash on the limb (edge) indicated by the blue tick marks? Something might have struck Saturn, creating that brief flare of light.

Last year, astronomers detected a fast radio burst that got them excited as to a new discovery, but confused them as to the signal's power

When they pinpointed the signal it turned out to be... a #NASA satellite that died in 1964

They have some good theories as to how the zombie satellite fired off some signals but us #StarTrek fans know what's going on

🚨 Astronomers have witnessed the dawn of a new solar system!

Using ALMA and JWST they observed the first specks of planet-forming material — hot minerals beginning to solidify around HOPS-315, a baby star 1300 light-years away.

This marks the first time a planetary system has been identified at such an early stage in its formation – a window to the past of our own Solar System.

New instance, new #introduction !

Hi #fediverse ! We’re the European Southern Observatory, and we design, build and operate ground-based telescopes.

One of them is our Extremely Large Telescope, currently under construction in #Chile. It will have a 39 m mirror, and its rotating enclosure will weigh 6100 tonnes, or about 700 mastodons!

We’re looking forward to chatting with all of you about #astronomy

And many thanks to @sebinthestars for running our former instance!

The sliding doors of the dome are open, revelaning the telescope inside: a cylindrical structure of white criss-crossed beams. The dome is surrounded by huge cranes, and the entire scene is bathed in the golden light of the setting Sun in the background.

Ignore this post. I need to pin my bio hashtags in a post because the bio links frustratingly break out of the advanced web view in this Mastodon build and they're my shortcut way of browsing posts. Hoping they fix this in a later build.

Maria Mitchell: America’s First Woman Astronomer and Mentor to Women in Science

As Vassar College’s first astronomy professor, Maria Mitchell advanced opportunities for women in science and mentored a generation of students using one of the country’s finest observatories.

$Postcard showing a woman sitting on the observing chair in front of a large refracting telescope. The accompanying text reads, “Prof. Maria Mitchell in the Observatory at Vassar College. June 1878.” The back is divided, with space for the address on the right and space for a message on the left. It is marked “Printed in Germany for Henry S. Wyer, Nantucket, Mass., U.S.A. No. 582” and indicates that a 1¢ stamp is required for domestic use and a 2¢ stamp for foreign use. Maria Mitchell (1818-1889) was America’s first woman astronomer, America’s first woman scientist of note, and the first professor of astronomy at Vassar College. Henry Sherman Wyer (1847-1920) was a photographer from Nantucket who published many of the earliest postcards of that island community. He was also active in the Nantucket Historical Society and the Maria Mitchell Association. While the photograph on this postcard was taken in 1878, the postcard was published between March 1, 1907, (when postcards with a divided back were first permitted in the U.S.) and 1917 (when the domestic postage for a postcard was raised to 2¢). https://www.si.edu/object/postcard:nmah_1372087$
