Astronomers Catch Black Hole Spewing Matter After Feeding

Black holes are some of the most awe-inspiring and mysterious celestial objects in the universe. This is primarily because astronomers still don’t understand the underlying mechanisms that drive black holes, including its formation, evolution, and end. As their name implies, black holes can’t be viewed directly since they blend into the background of the vastness of space. Therefore, astronomers are limited to “seeing” black holes when they consume other celestial objects, most notably stars. When this happens, the astronomers see the light from the star being violently consumed by a nearby black hole in a spectacular display. However, astronomers are still puzzled regarding what happens after the consumption.

More Data and Machine Learning has Kicked SETI Into High Gear

For over sixty years, astronomers and astrophysicists have been engaged in the Search for Extraterrestrial Intelligence (SETI). This consists of listening to other star systems for signs of technological activity (or “technosignatures), such as radio transmissions. This first attempt was in 1960, known as Project Ozma, where famed SETI researcher Dr. Frank Drake (father of the Drake Equation) and his colleagues used the Robert C. Byrd Green Bank Telescope in West Virginia to conduct a radio survey of Tau Ceti and Epsilon Eridani. Since then, the vast majority of SETI surveys have similarly looked for narrowband radio signals since they are very good at propagating through interstellar space. However, the biggest challenge has always been how to filter out radio transmissions on Earth – aka. radio frequency interference (RFI). In a recent study, an international team led by the Dunlap Institute for Astronomy and Astrophysics (DIAA) applied a new deep-learning algorithm to data collecte...

Planetary Surfaces: Why study them? Can they help us find life elsewhere?

Universe Today recently explored the importance of studying impact craters and what they can teach us about finding life beyond Earth. Impact craters are considered one of the many surface processes—others include volcanism, weathering, erosion, and plate tectonics—that shape surfaces on numerous planetary bodies, with all of them simultaneously occurring on Earth. Here, we will explore how and why planetary scientists study planetary surfaces, the challenges faced when studying other planetary surfaces, what planetary surfaces can teach us about finding life, and how upcoming students can pursue studying planetary surfaces, as well. So, why is it so important to study planetary surfaces throughout the solar system? “Planetary surfaces record the history of the Solar System, a history that’s almost entirely lost to us here on Earth,” Dr. Paul Byrne, who is an Associate Professor of Earth, Environmental, and Planetary Sciences at Washington University in St. Louis, tells Uni...

The First Close-Up Picture of Star Outside the Milky Way

Like a performer preparing for their big finale, a distant star is shedding its outer layers and preparing to explode as a supernova. Astronomers have been observing the huge star, named WOH G64, since its discovery in the 1970s. It’s one of the largest known stars, and also one of the most luminous and massive red supergiants (RSGs). The star is surrounded by an envelope of expelled star-stuff, which could indicate it’s getting ready to explode. WOH G64 isn’t in the Milky Way; it’s in the Large Magellanic Cloud (LMC), the Milky Way’s largest satellite galaxy. Getting these detailed image is quite a feat for the ESO’s Very Large Telescope Interferometer. It’s also quite an accomplishment for the team of scientists behind the image. They’ve published their images and the results of their observations of the star in the journal Astronomy and Astrophysics. Their research is titled “ Imaging the innermost circumstellar environment of the red supergiant WOH G64 in the Large Magellanic ...
