Unknown objects at the heart of the Milky Way are beaming radio signals, then mysteriously disappearing

The radio telescope at the Parkes Observatory at sunset near the town of Parkes, Australia, July 15, 2019.Stefica Nicol Bikes/Reuters Mysterious radio waves emanating from the center of the galaxy have astronomers stumped. Four objects have briefly emitted radio signals that don't resemble any known type of star. Scientists think each of the four signals could come from a new type of object unknown to astronomy. Ziteng Wang found a needle in an astronomical haystack.Wang, a physics PhD st...

A 19th-century artist's astronomical drawings are stunningly accurate. Compare them to NASA images today.

The Orion nebula, as Etienne Léopold Trouvelot drew it (left), and as NASA telescopes captured it (right). E. L. Trouvelot, from The New York Public Library; NASA/JPL-Caltech/STScI French artist Etienne Léopold Trouvelot sketched gorgeous illustrations of planets, star clusters, meteor showers, and eclipses in the 19th century. He worked for the Harvard College observatory, using a telescope with a grid etched into the glass eyepiece and sketching his astronomical observations on grid pape...

Astronomers spotted a distant planet in the middle of making its own moon

The PDS 70 system, located nearly 400 light-years away and still in the process of being formed, with planet PDS 70c circled in blue. ALMA (ESO/NAOJ/NRAO)/Benisty et al. Astronomers have captured a distant planet adorned with a moon-making disc for the first time. The planet has captured enough gas and dust in its orbit to make three moons the size of Earth's. By studying this world and its star, astronomers can learn more about how planets and moons are born. See more stories on Insid...

Mystery solved: Betelgeuse, the dimming star that drew international attention, isn't exploding - it was just dusty

These images, taken by the Very Large Telescope, show the surface of the red supergiant star Betelgeuse during its dimming from January 2019 (far left) to March 2020 (far right). ESO/M. Montargès et al. Betelgeuse, a distant red giant star, captured the world's attention last year because it was dimming. The star's dying light indicated that it might soon explode in a supernova. But a new study reveals that's not the case - it was just veiled in a cloud of dust. See more storie...

Astronomers spotted a galaxy dying after a major collision. It's bleeding out 10,000 suns' worth of gas each year.

An artist's impression shows galaxy ID2299 losing a tail of gas after being formed in a galactic collision. ESO/M. Kornmesser Astronomers can see a distant galaxy dying as it bleeds cold gas into space. Such gas is critical for forming stars. Galaxies die when they can no longer do so. This galaxy formed from a collision in which two galaxies merged into one. That left a "tail" that's shedding 10,000 suns' worth of gas each year. Visit Business Insider's homepage for more stories.

Fast radio bursts were once thought to be alien broadcasts. New research suggests the mysterious signals come from dead stars.

The super-dense remains of a dead star, as captured by NASA observatories. NASA/JPL-Caltech/ESA/CXC/Univ. of Ariz./Univ. of Szeged Astronomers have linked a mysterious fast radio burst to its source for the first time: a dead star within our galaxy. The dead star, known as a magnetar, released an explosion of X-rays and gamma rays with a single radio burst. The discovery suggests that these mysterious radio signals all come from magnetars.

Any aliens living around 1,004 nearby stars should be able to see the signs of life on Earth, a study says

An artist's impression shows exoplanet K2-18b, its host star, and an accompanying planet in the system. K2-18b is a super-Earth that hosts both water and temperatures that could support life. ESA/Hubble, M. Kornmesser Astronomers have identified 1,004 sun-like stars that could have Earth-like planets in their orbits. Any intelligent aliens on those exoplanets would be able to detect the signs of life on Earth. The researchers say these stars could be prime targets in the search for ali...

NASA's Hubble space telescope captured the ribbon of a supernova blast that ancient humans saw about 15,000 years ago

A Hubble Space Telescope photo shows a small section of the Cygnus supernova blast wave. ESA/Hubble/NASA/W. Blair The supernova explosion of a massive, dying star was so bright that ancient humans would have seen it from Earth about 15,000 years ago. The supernova's blast wave continues to scream through space, heating and compressing dust and gas in a way that causes them to glow in a web of colorful ribbons called the Cygnus Loop. NASA's Hubble space telescope recently captured an image ...

A Dusty Burp Could Explain Mysterious Dimming of Supergiant Star Betelgeuse

Doomed supergiant star Betelgeuse has been acting strange lately, appearing far less bright than usual and then bouncing back to normal. Hubble Space Telescope observations from last year suggest the unexpected dimming was caused by a sudden ejection of hot gases, which formed an enormous dust cloud after cooling.Read more...

Oh Yeah, Betelgeuse Is Definitely Looking Weirder

At this point, we’re all crossing our fingers that the dying star Betelgeuse will hurry up and explode already, because who doesn’t love a good show? The red giant star (visible in the constellation Orion) has been growing dimmer since late last year, leading many to speculate it could soon go supernova. Scientists…Read more...

High-Definition Video of the Sun’s Strange Surface

Captured using Hawaii’s Daniel K Inouye Solar Telescope (the world’s largest), this high-definition video of the sun’s surface is the closest observation earthlings have ever seen. Comprised of cell-like eruptions marked by bright centers and darker outlines, this particular swatch of the sun comprises 200 million square kilometers, and each individual “cell” is equal to the size of France. The first of many videos to …
