The Hubble constant, a set number that connects a galaxy’s speed to its distance from Earth and tells us how fast the ...

NASA has discovered the ten oldest galaxies. These galaxies offer a glimpse into the early universe. GN-z11 is the oldest, formed 400 million years after the Big Bang. UDFy-38135539 marks the ...

The early universe managed to produce some absolute monsters, even in relatively tiny galaxies ... may not fully explain how holes of this magnitude form and grow. “It’s possible that ...

Merging Gas-rich Galaxies That Harbor Low-luminosity Twin Quasars at z = 6.05: A Promising Progenitor of the Most Luminous Quasars. The Astrophysical Journal , 2024; 972 (1): 116 DOI: 10.3847/1538 ...

If we can see at most 3% of the universe, how can we estimate the total number of galaxies in it? When you purchase through links on our site, we may earn an affiliate commission. Here’s how it ...

The blue squares are the Large and Small Magellanic Clouds, and the red circles are other satellite galaxies. The fainter their absolute visual magnitude, the smaller the dot size. Credit: NAOJ/Tohoku ...

In the James Webb Space Telescope’s newest image, a pair of galaxies are smashing together, triggering waves of new star formation. And in the bright heart of the collision, we may be witnessing ...

The JWST can see galaxies with magnitudes of 34 ... There are times when it's more important to talk about an object's absolute magnitude. A star that is relatively close to Earth will appear ...

One likely reason is that the Miras in other galaxies used the same distance modulus ... Although we used the light curve correction to obtain the mean magnitude in the NIR band for Miras, the ...
