Epoch

Using the unique infrared sensitivity of NASA's James Webb Space Telescope, researchers can examine ancient galaxies to probe secrets of the early universe.

The celestial equivalent to latitude and longitude lets astronomers find their way across the heavens

Nicknamed the Firefly Sparkle, the newly-discovered galaxy existed approximately 600 million years after the Big Bang and consisted of a least 10 star clusters.

The universe's light-starved early epochs, as well as the first stars and galaxies, lie beyond the reach of conventional observatories but could be revealed by a new generation of radio telescope arrays

Although time might seem to pass slowly in some instances, it's important to remember that our Universe has been around for a long time. It's been 13.8 billion years since the hot Big Bang, and our…

By studying ancient, supermassive black holes called quasars, MIT PhD student Dominika Ďurovčíková is illuminating an early moment in the universe, when the galaxies could first be observed.

Astronomers have performed a comprehensive chemical study of a Galactic globular cluster known as Terzan 6. Results of the study, presented in a research paper published June 11 on the pre-print server arXiv, could advance our knowledge about the properties and nature of this cluster.

NASA's James Webb Space Telescope observed an unusually large and highly luminous galaxy at a record-breaking 290 million years after the big bang

Astronomers using the NASA/ESA Hubble Space Telescope have captured a striking image of NGC 2005, a globular cluster located 162,000 light-years away from Earth in the constellation of Dorado.

Astrophysicist Priyamvada Natarajan predicted that black holes can form without the help of stars. New observations support her theory

Primordial black holes left over from the Big Bang and no wider than a dime could be a prime target for NASA's Nancy Grace Roman Telescope after it launches ...

Astronomers using the Webb telescope (JWST) have found a very early massive galaxy being formed through galactic mergers.

The next year of science for the James Webb Space Telescope has been selected. It includes remote galaxy observations and, at last, a hunt for exomoons

Astronomers using the James Webb Space Telescope have detected the oldest "dead" galaxy ever observed, at just 700 million years after the Big Bang. The stalled-out relic defies explanation by our current knowledge of the early cosmos.

Astronomers have discovered a radio signal from a 'JuMBO' in the Orion nebula, a weird celestial object discovered by the James Webb Space Telescope that...

Employing massive data sets collected through NASA's James Webb Space Telescope, a research team led by a Rutgers University–New Brunswick astronomer is unearthing clues to conditions existing in the early universe.

Comet Wild 2 formed 4.5 billion years ago and is a relic of the birth of the solar system. In 2006, NASA brought pieces of it down to Earth.

This year's most interesting space images include infrared views of galactic "bones," an asteroid's double moon, Jupiter's giant polar vortex, and more

Astronomers have found the most distant Milky Way look-alike we've seen the universe, challenging theoretical predictions of galaxy evolution.

To understand the universe, we need to understand the extreme processes that shape it and drive its evolution. Things like supermassive black holes (SMBHs,) supernovae, massive reservoirs of dense gas, and crowds of stars both on and off the main sequence. Fortunately there's a place where these objects dwell in close proximity to one another: the Milky Way's galactic center (GC.)
