Galactic Coordinate System

With radio and infrared telescopes, astronomers can pierce the dusty veil of our galaxy and map its farthest reaches

Use the Great Square of Pegasus to locate Fomalhaut. Then you're on your way to looking out our galaxy's south window into intergalactic space. The post Galaxy's south window looks into intergalactic space first appeared on EarthSky.

NASA's Fermi Space Telescope presents a 14-year time-lapse movie, revealing the dynamic universe through gamma-ray imaging. It highlights the Milky Way's gamma-ray glow, solar flares, and distant galaxies powered by black holes. The cosmos comes alive in an all-sky time-lapse movie made from 14 y

The astrophysicists, from Trinity and the Breakthrough Listen team and Onsala Space Observatory in Sweden, are scanning the universe for "technosignatures" emanating from distant planets that would provide support for the existence of intelligent, alien life.

Astronomers have detected high-energy neutrinos coming from within our Milky Way galaxy, potentially opening up an exciting new window of research.

Led by INAF and Macquarie University, a portion of our Galaxy has been imaged in great detail as part of the PEGASUS survey - a radio astronomy project designed to discover more about the Milky Way

When we see spiral galaxies, some are face-on, others are edge-on, but most are tipped at an angle. But which side is closest to us? Remarkably, just by a visual inspection, you can conclude — with…

How astronomers solved the "Zone of Avoidance" puzzle. Astronomers see spiral and elliptical nebulae nearly everywhere, except by the Milky Way's plane. We didn't know why until the 20th….

The epic race inside the Pillars of Creation is almost over. The last infant stars are finishing their formation inside these pillars of gas. The evaporation of those columns is almost complete..

See this cosmic bird in flight in NASA's picture of the day!

The video was created from the 14 years of data collected by Fermi's Large Area Telescope (LAT).

The galactic bulge at the heart of the Milky Way is haunted by the ghosts of dead stars spread out as a mysterious arrangement of planetary nebulas.

Using the MeerKAT telescope, an international team of astronomers has serendipitously discovered a new pulsar. The newfound object, designated PSR J1710−3452, turns out to be an extremely intermittent radio pulsar. The finding was reported June 19 on the pre-print server arXiv.

With no other galaxies in its vicinity for ~100 million light-years in all directions, it's as isolated and lonely as a galaxy can be.

The Milky Way is our home galaxy in the vast universe, but the structure and composition of the Milky Way remain mysterious. The vast interstellar space between the billions of stars is not empty, but filled with tenuous interstellar medium. The diffuse hydrogen gas radiates a spectral line with a frequency of around 1420 MHz. Some dense hydrogen atoms gather to form clouds of molecular hydrogen, and newly born…

A 3D map of our cosmic neighborhood has revealed hot and cold regions as well as an "escape tunnel" from our local bubble.

In the chaotic environment of open star clusters, strong gravitational interactions between bodies can launch individual stars far outside the cluster, even outside our galaxy, the Milky Way. Now, for the first time researchers have mapped several of those stars, which exist outside the galaxy's disk, to the clusters of their origin using new data from the European Space Agency's Gaia Mission.

As Marcel Proust said, "The real voyage of discovery...consists not in seeking new landscapes, but in having new eyes."
