It Turns Out, Andromeda is Younger Than Earth… Sort Of Since ancient times, astronomers have looked up at the night sky and seen the Andromeda galaxy. As the closest galaxy to our own, scientists have been able to observe and scrutinize this giant spiral galaxy for millennia. By the 20th century, astronomers realized that Andromeda was the Milky Way’s sister galaxy and was moving towards us. In 4.5 billion years, it will even merge with our own to form a supergalaxy. However, it seems astronomers were wrong about the Andromeda galaxy in one major respect. According to recent study led by a team of FrenchRead More →

Interstellar Asteroid ‘Oumuamua Had a Violent Past On October 19th, 2017, the Panoramic Survey Telescope and Rapid Response System-1 (Pan-STARRS-1) telescope in Hawaii announced the first-ever detection of an interstellar asteroid – I/2017 U1 (aka. ‘Oumuamua). Originally mistaken for a comet, follow-up observations conducted by the European Southern Observatory (ESO) and others confirmed that ‘Oumuamua was actually a rocky body that had originated outside of our Solar System. Since that time, multiple investigations have been conducted to determine ‘Oumuamua’s structure, composition, and just how common such visitors are. At the same time, a considerable amount of attention has been dedicated to determining the asteroid’s origins.Read More →

Astrophotographer Captures Musk’s Tesla Roadster Moving Through Space An astrophotographer in California has captured images of Elon Musk’s Tesla Roadster on its journey around our Sun. In the early morning of February 9th, Rogelio Bernal Andreo captured images of the Roadster as it appeared just above the horizon. To get the images, Andreo made use of an impressive arsenal of technological tools. Andreo knew that photographing the Roadster would be a challenge, since it was over a million miles away at the time. But he has the experience and equipment to pull it off. The first task was to determine where the Tesla would beRead More →

What are the Chances Musk’s Space Tesla is Going to Crash Into Venus or Earth? On February 6th, 2018, SpaceX successfully launched its Falcon Heavy rocket into orbit. This was a momentous occasion for the private aerospace company and represented a major breakthrough for spaceflight. Not only is the Falcon Heavy the most powerful rocket currently in service, it is also the first heavy launch vehicle that relies on reusable boosters (two of which were successfully retrieved after the launch). Equally interesting was the rocket’s cargo, which consisted of Musk’s cherry-red Tesla Roadster with a spacesuit in the driver’s seat. According to Musk, this vehicleRead More →

Witness The Power Of A Fully Operational ESPRESSO Instrument. Four Telescopes Acting As One It’s been 20 years since the first of the four Unit Telescopes that comprise the ESO’s Very Large Telescope (VLT) saw first light. Since the year 2000 all four of them have been in operation. One of the original goals of the VLT was to have all four of the ‘scopes work in combination, and that has now been achieved. The instrument that combines the light from all four of the VLT ‘scopes is called ESPRESSO, which stands for Echelle SPectrograph for Rocky Exoplanet and Stable Spectroscopic Observations. ESPRESSO captures theRead More →

Mars 2020 Rover is Going to be Taking a Chunk of Mars Back to… Mars? In July of 2020, the Mars 2020 rover – part of NASA’s Mars Exploration Program – will begin its long journey to the Red Planet. Hot on the heels of the Opportunity and Curiosity rovers, the Mars 2020 rover will attempt to answer some of the most pressing questions we have about Mars. Foremost among these is whether or not the planet had habitable conditions in the past, and whether microbial life ever existed there. To this end, the Mars 2020 rover will obtain drill samples of Martian rock and setRead More →
