Cosmic Tempest

Researchers using the Gemini North telescope on Hawai'i's Maunakea have detected the most energetic wind from any quasar ever measured.

Just as the sun has planets and the planets have moons, our galaxy has satellite galaxies, and some of those might have smaller satellite galaxies of their own.

Astronomers have found the best evidence for the perpetrator of a cosmic homicide: a black hole of an elusive class known as "intermediate-mass," which betrayed its existence by tearing apart a wayward star that passed too close.

Much of the progress in Astronomy has been driven by instrumental developments, from the first telescopes to fiber fed spectrographs.

Astronomers obtained the first resolved image of disturbed gaseous clouds in a galaxy 11 billion light-years away by using the Atacama Large Millimeter/submillimeter Array (ALMA).

Astronomers have captured new, detailed maps of three nearby interstellar gas clouds containing regions of ongoing high-mass star formation. The results of this survey, called the Star Formation Project, will help improve our understanding of the star formation process.

Quasar Tsunamis Rip Across Galaxies

Using the unique capabilities of NASA's Hubble Space Telescope, a team of astronomers has discovered the most energetic outflows ever witnessed in the universe. They emanate from quasars and tear across interstellar space like tsunamis, wreaking havoc on the galaxies in which the quasars live.

Last April, the Event Horizon Telescope (EHT) sparked international excitement when it unveiled the first image of a black hole.

A New Type Of Pulsating Star Discovered

A star that pulsates on just one side has been discovered in the Milky Way about 1500 light years from Earth.

SOFIA's Infrared View of the Skies

The Stratospheric Observatory for Infrared Astronomy, SOFIA, studies the universe with infrared light.

The barred spiral galaxy NGC 3887, seen here as viewed by the Wide Field Camera 3 aboard the NASA/ESA Hubble Space Telescope, lies over 60 million light-years away from us in the southern constellation of Crater (the Cup).

ALMA Spots A Metamorphosing Aged Star

An international team of astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) has captured the very moment when an old star first starts to alter its environment.

A massive white dwarf star with a bizarre carbon-rich atmosphere could be two white dwarfs merged together according to an international team led by University of Warwick astronomers, and only narrowly avoided destruction.

Scientists studying a distant galaxy cluster have discovered the biggest explosion seen in the Universe since the Big Bang.

The Force Is Strong In Neutron Stars

Most ordinary matter is held together by an invisible subatomic glue known as the strong nuclear force -- one of the four fundamental forces in nature, along with gravity, electromagnetism, and the weak force. The strong nuclear force is responsible for the push and pull between protons and neutrons in an atom's nucleus, which keeps an atom from collapsing in on itself.

Hubble Fingerprints Galaxy NGC 4689

The NASA/ESA Hubble Space Telescope is no stranger to spiral galaxies. The telescope has brought us some of the most beautiful images ever taken of our spiral neighbors -- and the galaxy known as NGC 4689 is no exception.

An international team of astronomers led by scientists at the University of California, Riverside, has found an unusual monster galaxy that existed about 12 billion years ago, when the universe was only 1.8 billion years old, or 13 percent of its current age of 13.8 billion years.

Scientists at the Center for Astrophysics | Harvard & Smithsonian (CfA) have completed the Extremely Low Mass -- also known as ELM -- spectroscopic study of white dwarf stars in the Sloan Digital Sky Survey (SDSS).

NASA Scientist Al Kogut has found a way to do Hubble Space Telescope-class science from a relatively inexpensive scientific balloon and is well on the way to proving the concept.

An international team of astrophysicists led by Australian Professor Matthew Bailes, from the ARC Centre of Excellence of Gravitational Wave Discovery (OzGrav), has shown exciting new evidence for 'frame-dragging'.
