Astronomers say we may be witnessing a merger of two small galaxies just 400 million years after the Big Bang.
The galaxy cluster MACS0647 acts as a cosmic...
Dust is a key ingredient in both observed and physical properties of galaxies. It obscures and scatters stellar light, and enables star formation by acting...
The newly-discovered blue supergiant is much hotter than the Sun, and existed when the Universe was about 2.6 billion years old.

Earendel is a B-type giant star, a luminous blue variable star, or even a binary system with an extremely hot primary member, according to new observations...
Astronomers from the University of Cambridge and elsewhere have analyzed the spectroscopic and photometric data from three instruments (NIRSpec, NIRISS...
Astronomers using the NASA/ESA/CSA James Webb Space Telescope have spotted ancient globular clusters around a remarkable galaxy that is strongly gravitationally...
Earendel emitted its light approximately 900 million years after the Big Bang.

Using the Atacama Large Millimeter/submillimeter Array (ALMA), astronomers have observed a significant amount of cold, neutral gas in the outer regions...
In April 2019, the Event Horizon Telescope (EHT) Collaboration released stunning images of M87*, a 6.5-billion-solar-mass black hole in the center of the...
In a new paper in the Astrophysical Journal, a duo of astronomers from the Kavli Institute for Particle Astrophysics and Cosmology at Stanford University...
Designated WHL0137-LS and nicknamed Earendel, the newly-detected star emitted its light around 900 million years after the Big Bang.
Earendel (arrow) is...
Fluorine is one of the most interesting elements for nuclear and stellar astrophysics. Fluorine abundance was first measured for stars other than the Sun...
