Today we push our aging curiosity out into the Solar System to ask that simple question: how old is it and how do we know?

Located in the vicinity Ursa Major constellation, roughly 12 million light years from Earth, is the starburst galaxy known as the Messier 82 (aka. the Cigar Galaxy). The post Messier 82 – the Cigar Galaxy appeared first on Universe Today

Recent observations have revealed a pulsar that appears to have been accelerated by the very supernova explosion that created it. The post Pulsar Seen Speeding Away From the Supernova That Created it appeared first on Universe Today .

After undergoing upgrades, the LIGO observatory will be going back online this April, with “almost daily” detections of gravitational wave events expected. The post LIGO Just Got a Big Upgrade, Will Begin Searching for Gravitational Waves Again on April 1st appeared first on Universe Today

It’s too bad Mars is such an interesting place, because it’s actually one of the most difficult places to visit in the Solar System, especially if you want to bring along a lot of luggage. That planet is a graveyard of missions that didn’t quite make it.

The SIRIUS-19 experiment recently kicked off, with six cosmonauts entering a simulated lunar environment (where they will spend the next 122 days conducting experiments).

A new discovery in South America has added further weight to the Young Dryas Impact theory, which states that a sudden shift in its climate 12,800 years ago was due to a comet hitting Earth. The post Almost 13,000 Years Ago, a Comet Impact Set Everything on Fire appeared first on Universe Today .

The milestones just keep coming for SpaceX. After the recent successful test flight of the Crew Dragon capsule, another of SpaceX’s ventures is about to meet its own milestone.

A ghost from the old Soviet space program may return to Earth in the coming years. Mimicking a campy episode of the 70s series The Six Million Dollar Man, a Soviet Venus lander stranded in Earth orbit will eventually reenter the atmosphere, perhaps as early as late 2019

Welcome back to Messier Monday! Today, we continue in our tribute to our dear friend, Tammy Plotner, by looking at the Bode’s Galaxy – also known as Messier 81! During the 18th century, famed French astronomer Charles Messier noticed the presence of several “nebulous objects”  while surveying the night sky. Originally mistaking these objects for … Continue reading “Messier 81 – the Bode Galaxy” The post Messier 81 – the Bode Galaxy appeared first on Universe Today .
