Strange Activity Detected Around Milky Way's Supermassive Black Hole

Astrophysicists Gustavo Magallanes-Guijón and Sergio Mendoza from the National Autonomous University of Mexico have observed a distinct pattern: every 76.32 minutes, gamma-ray signals emanate from the vicinity of Sagittarius A*.

Space

Hubble Space Telescope Captures a Striking Image of Three Interacting Galaxies

These three galaxies, located approximately 500 million light-years away from Earth in the constellation Tucana, are engaged in a gravitational tango, prompting astronomers to label them as a "merging group."

Space

A New Cosmic Atlas Reveals Stunning Details of 400,000 Nearby Galaxies

The Siena Galaxy Atlas is poised to become a valuable resource for astronomers, enabling them to analyze various aspects of the universe's structure, from galaxy formation and evolution to the distribution of enigmatic dark matter.

Space

Hubble Telescope Captures an Unexplained Cosmic Explosion Between Galaxies

This brilliant burst of blue light, an exceedingly rare phenomenon, occurred in an unexpected location, far removed from any host galaxy, challenging what astronomers thought they knew about these events.

Space

James Webb Space Telescope Captures New Images of the Whirlpool Galaxy

Combining both the MIRI and NIRCam images into a composite photo reveals a rich tapestry of details, providing valuable insights into the interplay between stellar feedback and star formation in extragalactic environments.

Space

James Webb Space Telescope Discovers the Earliest-Known Carbon Dust

This revelation challenges existing theories on the chemical evolution of the universe, as the detection suggests that galaxies formed and enriched with carbon much more rapidly than previously believed.

Space

Astronomers Created a New Detailed Map of the Milky Way

The map is comprised of 21,400 individual exposures, with a final image showing a huge 3.32 billion celestial objects. The collected data accounts for around 6.5 percent of the entire night sky.

Space

The Milky Way May Have a Different Shape Than We Previously Thought

After a detailed study of the collected and systematized data, scientists suggested that the Milky Way is a spiral galaxy with only two main arms extending from a centralized cluster of stars.

Space

Hubble Space Telescope Spots a Rare View of 3 Galaxies About to Collide

This colliding trio, collectively known to astronomers as SDSSCGB 10189, is a relatively rare combination of three large star-forming galaxies only 50,000 light-years apart. According to scientists, this is an extremely small distance on a cosmic scale.

Space

Astronomers Discover a "Mirror Image" of the Milky Way from Billions of Years Ago

Using the James Webb Space Telescope, astronomers have discovered a galaxy that looks very similar to our Milky Way in its early stages of evolution. It was named the Sparkler because almost two dozen glittering globular clusters orbit it.

Space

Astronomers Capture a Radio Signal from an Extremely Distant Galaxy

This discovery was made possible by a phenomenon called gravitational lensing, in which light emitted by a source is bent by the presence of another massive body, effectively amplifying the signal, the astronomers explain.

Space

Scientists Discover Two Supermassive Black Holes in Merging Galaxies

It will take several hundred million years for this particular pair of black holes to collide, but the insight gained from this observation could help scientists better estimate how many pairs of black holes in the universe are close to colliding.

Space

Hubble Space Telescope Captures Celestial Fireworks Left by a Star's Death

The image shows intertwined strands of blue and orange that are the remnants of the supernova DEM L 190. The structure is located in the Milky Way's companion galaxy, the Large Magellanic Cloud, and hides a rapidly spinning neutron star.

Space

Astronomers Created a New Interactive Map of the Universe

The full map of the observable universe is actually a slice of cosmos with a thickness of about 10 degrees. However, it still gives an idea of the scale of our universe as well as its stars and galaxies up to 13.7 billion light-years away.

Space

James Webb Telescope Spotted Two Unusually Bright Galaxies from the Early Universe

The galaxies are extremely bright, and one of the reasons for this may be that they could have been very massive, with lots of low-mass stars. Or they could be much less massive, consisting of a smaller number of extremely bright Population III stars.
