A distant galaxy that lay quiet for decades has suddenly stirred, lighting up in dramatic bursts that have caught astronomers ...

the heating mechanisms affecting gas within just a few hundred light years of the black hole. According to the scientists, the observations help researchers better understand the extreme ...

Despite residing in one of the galaxy's most extreme star-forming environments — just 200 light-years from the supermassive black hole Sagittarius A* — and containing vast reserves of molecular gas, ...

Scientists have observed a previously inactive supermassive black hole producing regular, powerful X-ray eruptions that ...

Astronomers tallying up all the normal matter—stars, galaxies and gas—in the universe today have come up embarrassingly short ...

Uncover the insights gained from the Webb telescope about early galaxies and their role in illuminating the universe.

If dark matter is creating positrons in the CMZ, those particles will eventually slow down and eventually annihilate with electrons in the environment, producing gamma-rays at exactly 511keV energy.

GS-z13-1, marks the earliest sign yet spotted of the era of cosmic reionization at 330 million years after the Big Bang.

Scientists have discovered a colossal water reservoir in space, containing as much water as 100 trillion times all the oceans on Earth combined. This enormous water body is located near the active ...

Most people know that black holes are kind of scary. Admittedly, that's true, but black holes are so much more than that.

Webb first observed the region called Sagittarius C in 2023. Now researchers are now using those observations to study star formation in the wider area around the center of the Milky Way, known as the ...

The spiral galaxy 2MASX J23453268−0449256 is located nearly 1 billion light-years away from Earth, and measures about three ...
