#UMPlus - Messier 17 by Frank Sackenheim

universomagico.net/2025/04/mes

This excellent image by astronomer Frank Sackenheim shows the Messier 17 nebula, also cataloged as Gum 81 and Sh2-45. This nebula is ionized by ultraviolet radiation from the young stars in the open star cluster NGC 6618. Messier 17's shape has been sculpted by the stellar winds from these same.....

#UMPlus - The Heart of Sh2-284

universomagico.net/2025/04/el-

This infrared image, taken by the Hubble Space Telescope, shows a small portion of the Sh2-284 emission nebula, which can be seen here in its entirety. This immense region of gas and dust is a birthplace for stars, which shine brightly among the clouds of gas and dust. Bright clusters of newborn stars glow.....

The Heart of Sh2-284

ESO

The laser beams of our Very Large Telescope pierce the star-filled sky of the Atacama Desert in #Chile

The lasers create artificial "stars" in the atmosphere, about 90 km above the ground, which then act as guides. By studying how they are blurred by the atmosphere, the telescope's deformable secondary mirror quickly reshapes itself in real time, yielding very sharp images. It’s almost as good as sending the VLT up into space!

A large telescope stands in the centre of the image, against a backdrop of thousands of stars above a desert landscape. The Milky Way galaxy is visible behind the telescope, and the sky itself glows slightly green towards the horizon. From the very centre of the telescope, four bright orange laser beams are projected ahead into the night sky.

#UMPlus - Meteorite explodes over Hawaii

universomagico.net/2025/04/un-

Meteor showers are events in which the sky is filled with trails of cosmic dust, created by material left behind by comets and asteroids that have passed close to Earth's orbit. Occasionally, however, single, slightly larger meteorites appear, which can be a few centimeters in size, large enough to produce an.....

#UMPlus - #UMPlus - A Planet Destroyed in Helix

universomagico.net/2025/04/un-

On March 4, 2025, the Chandra X-ray Observatory revealed this image of the Helix Nebula, at the center of which is a mysterious X-ray emission. Astronomers have studied this nebula for over 40 years, and this is the first time such an event has been observed at the center of a planetary nebula. A.....

#UMPlus - Palomar 13 by Gregg Ruppel

universomagico.net/2025/04/pal

This image by astronomer Gregg L. Ruppel shows two objects that are as intriguing as they are intriguing. There are many objects in the sky, especially in the Milky Way's halo, whose nature is unclear. Some of these objects are difficult to approach observationally, and for others, there is simply no.....
