Giant Bubbles Expanding From The Milky Way Could Be Explained by a Single Event

by

Two sets of giant bubbles that extend thousands of light-years above and below the plane of the Milky Way could have been produced by the same event, in spite of their significant difference in size.   They’re called the Fermi bubbles and the eROSITA bubbles, and astronomers believe they were the result of activity by … Read more

Largest shock wave in the universe is ’60 times larger than the Milky Way,’ new study finds

Cosmic detectives investigate the origins of Milky Way material

by

By studying light from hundreds of thousands of stars in the Milky Way, scientists have revealed where the pieces that make up our galaxy came from.  In a new study, scientists broke the light coming from 600,000 stars into spectra that determine the stars’ chemical composition. In doing this, they were able to reveal which … Read more

James Webb Space Telescope will study Milky Way’s flaring supermassive black hole

by

The James Webb Space Telescope will study the weirdly flickering black hole at the heart of our galaxy, the Milky Way, which has proved elusive for existing telescopes to explore.  Webb will join the efforts of numerous telescopes to understand the nature of the supermassive black hole called Sagittarius A*, whose tendency to flare up … Read more

The Milky Way’s Dramatic History of Violence Has Been Charted in a New Map

by

Over the course of the history of the Universe, the Milky Way has not been serenely sailing through intergalactic space. Quite the contrary, actually. Over the last 13.6 billion years or so, it has collided with and consumed multiple other galaxies.   Now, through painstaking work, astronomers led by Khyati Malhan of the Max Planck … Read more

Astronomers spot remains of long-lost galaxy eaten by the Milky Way

by

The Milky Way galaxy feasted on more galaxies in its early days than astronomers thought. The Gaia spacecraft uncovered the remains of an ancient cosmic collision in our Milky Way, revealing a previously unknown galaxy, now nicknamed “Pontus,” absorbed by the Milky Way long before our galaxy looked the way it does now. Pontus was … Read more
