Awakening Newborn Stars

Lying inside our home galaxy, the Milky Way, this Herbig-Haro object is a turbulent birthing ground for new stars in a region known as the Orion B molecular cloud complex, located 1,350 light-years away.

A Blazar In The Early Universe

The supersharp radio "vision" of the National Science Foundation's Very Long Baseline Array (VLBA) has revealed previously unseen details in a jet of material ejected at three-quarters the speed of light from the core of a galaxy some 12.8 billion light-years from Earth.

Christmas Tree Cluster

Newborn stars, hidden behind thick dust, are revealed in this image of a section of the so-called Christmas Tree Cluster from NASA's Spitzer Space Telescope.

Artificial intelligence is classifying real supernova explosions without the traditional use of spectra, thanks to a team of astronomers at the Center for Astrophysics | Harvard & Smithsonian. The complete data sets and resulting classifications are publicly available for open use.

An international group of scientists, including Case Western Reserve University Astronomy Chair Stacy McGaugh, has published research contending that a rival idea to the popular dark matter hypothesis more accurately predicts a galactic phenomenon that appears to defy the classic rules of gravity.

The Hubble Space Telescope turned 30 this year, and for the occasion, it's sharing a present with you. NASA has just released dozens of newly processed Hubble images featuring 30 dazzling galaxies, sparkling star clusters, and ethereal nebulae.

Hubble Gazes Upon A Cosmic Wonderland

This large expanse of space captured with the Hubble Space Telescope features the galaxy SDSS J225506.80+005839.9.

The Gaia space telescope has measured the acceleration of the Solar System when it orbits the center of our Milky Way galaxy.

A unique stage of planetary system evolution has been imaged by astronomers, showing fast-moving carbon monoxide gas flowing away from a star system over 400 light years away, a discovery that provides an opportunity to study how our own solar system developed.

In 2018 an international team of researchers using the NASA/ESA Hubble Space Telescope and several other observatories uncovered, for the first time, a galaxy in our cosmic neighborhood that is missing most of its dark matter.

Researchers created a new astronomical instrument that has successfully aided in estimating the abundance of metals in the early universe.

The spiral-shaped disc of stars and planets is being pulled, twisted and deformed with extreme violence by the gravitational force of a smaller galaxy - the Large Magellanic Cloud (LMC).

Milky Way Family Tree

Galaxies like the Milky Way formed by the merging of smaller progenitor galaxies.

Long ago and far across the universe, an enormous burst of gamma rays unleashed more energy in a half-second than the Sun will produce over its entire 10-billion-year lifetime.

Although astronomers have been studying galaxy IC 5063 for decades, it took a non-scientist to make the surprising discovery.

Astronomers using data from the ongoing VLA Sky Survey (VLASS) have found a number of distant galaxies with supermassive black holes at their cores that have launched powerful, radio-emitting jets of material within the past two decades or so. The scientists compared data from VLASS with data from an earlier survey that also used the National Science Foundation's Karl G. Jansky Very Large Array (VLA) to reach their conclusion.

In 2004, scientists with NASA's Galaxy Evolution Explorer spotted an object unlike any they'd seen in our Milky Way Galaxy: a large, faint blob of gas that seemed to have a star at its center.

Cosmic Flashes Come In All Different Sizes

On May 24, four European telescopes took part in the global effort to understand mysterious cosmic flashes.

Theories on how the Milky Way formed are set to be rewritten following discoveries about the behaviour of some of its oldest stars.

How hot is the Universe today? How hot was it before?
