#UMPlus - Colors in the Sky by Tom Masterson

https://www.universomagico.net/2025/07/colores-en-el-cielo-por-tom-masterson.html

This image, taken by astronomer Tom Masterson, shows a landscape worthy of being from another planet, yet it's actually on Earth. The photographer chose the Los Padres National Forest, near Lockwood Valley, in California, United States. Los Padres is a favorite spot for adventurers hiking, camping, horseback.....

Heads-up: we have images of a new interstellar visitor!

Comet #3IATLAS is only the third object ever spotted coming from beyond our Solar System.

In this timelapse, our Very Large Telescope in #Chile observes the comet move across the night sky — just two days after its discovery!

#UMPlus - Reflection Nebula DG 41

https://www.universomagico.net/2025/07/nebulosa-de-reflexion-dg-41.html

This image, taken by the Hubble Space Telescope, shows a reflection nebula cataloged as DG 41. Reflection nebulae are cosmic dust clouds that do not emit their own light, as other nebulae do when they become ionized. Instead, radiation and winds from nearby stars collide with the dust, scattering it and also.....

#UMPlus - Infrared View of the Bullet Cluster

https://www.universomagico.net/2025/07/vista-infrarroja-del-cumulo-bala.html

All galaxies are made up of stars, gas, dust, and dark matter. The Bullet Cluster of Galaxies, seen in this James Webb Space Telescope image, is composed of two very massive groups of galaxies, known as galaxy clusters, that are gravitationally bound. This field of view is located in the direction of the.....

Messier 82, nicknamed the Cigar Galaxy, eclipses the Milky Way. This galaxy is located just 12 million light-years from the Milky Way and lies in the direction of the constellation Ursa Major. Despite being smaller than the Milky Way, M82 is five times more luminous than our galaxy and forms stars ten times.....

(02 Jul) New evidence that some supernovae may be a “double detonation”

It may be possible to blow up a white dwarf before it reaches a critical mass.

Investment in research made the U.S. a global leader in science, technology, healthcare and education. That's changing, thanks to unprecedented federal cuts and the defunding of institutions. As a university lecturer and member of the American Astronomical Society, astrophysicist Ethan Siegel is witnessing it first hand, and seeing a generational loss of science across practically every discipline. He writes for Big Think about what that could mean for the rest of the world. "Hitler’s destruction of his nation’s science in 1930s Nazi Germany wound up benefiting the rest of the world through an exodus of scientists that became known as Hitler’s gift," he writes. "Other nations are aware of the situation in the U.S. and across the world, and they’re stepping up to invest in science ... It is, after all, how the US became an economic and scientific superpower in the 20th and 21st centuries, and if our nation is going to abandon those principles, other countries will certainly reap those benefits."
