Welcome back to Messier Monday! In our ongoing tribute to the great Tammy Plotner, we take a look at the Messier 21 open star cluster. Enjoy! Back in the 18th century, famed French astronomer Charles Messier noted the presence of several “nebulous objects” in the night sky. Having originally mistaken them for comets, he began compiling a list of these objects so that other astronomers wouldn’t make the same mistake
SpaceX Falcon 9 rocket moments after catastrophic explosion destroys the rocket and Amos-6 Israeli satellite payload at launch pad 40 at Cape Canaveral Air Force Station, FL, on Sept. 1, 2016.
There’s a remote chance that inexplicable light variations in a star in the Northern Cross may be caused by the works of an alien civilization. 1,480 light years from Earth twinkles one of the greatest mysteries of recent times. There in the constellation Cygnus the Swan, you’ll find a dim, ordinary-looking point of light with an innocent sounding name — Tabby’s Star
In 2015, Russian billionaire Yuri Milner founded Breakthrough Initiatives with the intention of bolstering the search for extra-terrestrial life.
A closeup of the dark, approximately circular crater about 7.9 feet (2.4 meters) in diameter that marks the crash of the Schiaparelli test lander on Mars. The new, higher-resolution photo was taken on October 25 by NASA’s Mars Reconnaissance Lander (MRO).
Ever since the Voyager 2 made its historic flyby of Saturn, astronomers have been aware of the persistent hexagonal storm around the gas giant’s north pole. This a six-sided jetstream has been a constant source of fascination, due to its sheer size and immense power.
Host: Fraser Cain ( @fcain ) Special Guest: Dr. Derrick Pitts, Chief Astronomer and Director of the Fels Planetarium at The Franklin Institute. He has been a NASA Solar System Ambassador since 2009 and serves as the Astrobiology Ambassador for the NASA/MIRS/UNCF Special Program Corporation’s Astrobiology Partnership Program.
Finally, the New Horizons team has their entire “pot of gold.” 15 months after the mission’s flyby of the Pluto system, the final bits of science data from the historic July 2015 event has been safely transmitted to Earth. “The New Horizons mission has required patience for many years, but we knew the results would be well worth the wait,” New Horizons project scientists Hal Weaver told me earlier this year
Proxima b is the subject of a lot interest these days. And why not? As the closest extrasolar planet to our Solar System, it is the best shot we have at studying exoplanets up close in the near future.
Last week, ESA’s Schiaparelli lander smashed onto the surface of Mars . Apparently its descent thrusters shut off early, and instead of gently landing on the surface, it hit hard, going 300 km/h, creating a 15-meter crater on the surface of Mars
What is it going to take to really get humans to Mars? A new television series and a companion book take a detailed and hard look at the future of Mars exploration.
As you’ve probably noticed, the Moon looks different from one evening to the next. Sometimes we see a New Moon, when the Moon is enshrouded in shadow. At other times, we see a Full Moon, when the entire face of the Moon is illuminated
Ever since its existence was first proposed, the evidence for Planet 9 continues to mount. But of course, said evidence has been entirely indirect, consisting mostly of studies that show how the orbits of Trans-Neptunian Objects (TNOs) are consistent with a large object crossing their path. However, evidence is also emerging that comes from the center of the Solar System itself
Here’s a great new view of China’s Tiangong II space station, taken by a new ‘selfie’ satellite. The Banxing-2 satellite is about the size of a desktop printer and was released from the station on Sunday
Welcome, come in to the 480th Carnival of Space! The Carnival is a community of space science and astronomy writers and bloggers, who submit their best work each week for your benefit. I’m Susie Murph, part of the team at Universe Today and CosmoQuest. So now, on to this week’s stories! Over at Links Through Space, they conclude a series of 7 articles on the Age of Astronomy with our last article of the Ancient Astronomy Series: THE AGE OF ASTRONOMY.
The value of a good analyst is priceless.
If you’ve watched any Ren and Stimpy cartoons, you know that one of the greatest hazards of spaceflight is “space madness”. Only exposure to the isolation and all pervasive radiation of deep space could drive an animated chihuahua into such a state of lunacy.
This Halloween weekend’s top astronomical event features something that you won’t see in the sky. By now, you’ve probably seen the stories circulating ’round ye ole web about how this month features a ‘ Black Moon .’ The internet seems to love promulgating the passing of such curious calendrical oddities as Moons both Black, Blue and otherwise .
On a clear night, and when light pollution isn’t a serious factor, looking up at the sky is a breathtaking experience. On occasions like these, it is easy to be blown away by the sheer number of stars out there.
Ever since the Cassini probe arrived at Saturn in 2004, it has revealed some startling things about the planet’s system of moons.
