Hello, Ms. Nufer's class, and welcome to your very own blog about science! Since you're learning about astronomy right now, I'll keep you updated on news from the astronomy field. If you have…

The Antennae Galaxies, located in the constellation of Corvus (the Crow), are among the closest known merging galaxies. The two galaxies, also known as NGC 4038 and NGC 4039, began interacting a few…

A team of Dutch and German astronomers have discovered part of the missing matter in the Universe using the European X-ray satellite XMM-Newton. They observed a filament of hot gas connecting two…

A group of researchers writing in Geophysical Research Letters have a new theory about Mercury’s mysterious magnetic field - iron “snow” inside the planet that forms and falls toward the center, much…

The Earth's atmosphere is a gigantic prism that disperses sunlight. In the most ideal atmospheric conditions, such as those found regularly above Cerro Paranal, this will lead to the appearance of so…

It makes sense that massive black holes lurking in galactic nuclei and weighing millions of Suns can disrupt stars that come too close. Astrophysicists say that the black hole’s gravity pulls harder…

At the cores of many galaxies, supermassive black holes expel powerful jets of particles at nearly the speed of light. Just how they perform this feat has long been one of the mysteries of…

Data from the ESA/NASA spacecraft SOHO shows clearly that powerful starquakes ripple around the Sun in the wake of mighty solar flares that explode above its surface. The observations give solar…

Huge star streams in the outskirts of two nearby spiral galaxies have allowed astronomers to obtain a panoramic overview of ' galactic cannibalism' similar to that involving the Sagittarius dwarf…
