Image of three Milky Way-like galaxies and their systems of satellite galaxies. The SAGA survey identified two, six, and nine small satellite galaxies in these three systems respectively.

An image of a Milky Way-like galaxy and its system of satellite galaxies. The SAGA survey identified six small satellite galaxies in orbit around this Milky Way analog.

Astronomers have discovered a black hole emitting energy in jets longer than the width of 140 Milky Way galaxies.

And, if the timing is right, you might even see a hazy belt stretched across the sky—the starry, dusty core of our very own Milky Way galaxy. Right now is a peak time for United States-based ...

The Milky Way is home to gas, dust, billions of stars, and a supermassive black hole at its center. Living in this galactic ...

Since 2012, the Satellites Around Galactic Analogs (SAGA) Survey has studied the regions around 101 galaxies that are similar ...

However, the Milky Way is also spectacular this time of year. At about 9 p.m., look for three bight stars almost overhead; Altair, Deneb and Vega. Get away from city lights and you will see the ...

Astronomers have observed a massive pair of jets releasing from a supermassive black hole 7.5 billion light-years ...

"Clusters rich in red supergiants are very rare and tend to be very far away, but they play a crucial role in understanding key aspects in the evolution of massive stars." In the past, map makers ...

A new image from the James Webb Space Telescope depicts the "extreme outer galaxy" in unprecedented detail, NASA researchers ...

Galaxies are much bigger than we originally thought, extending far out into deep space — so far that the Milky Way likely interacts with our closest neighbor ...

Webb's imagery has enabled scientists to better study star formation in the outer Milky Way. A team of NASA astronomers recently pointed the spacefaring telescope toward the outskirts of our own ...
