We’re always interested in the surface features of the planets and moons in the Solar System, but that’s only skin deep. It turns out, these worlds have an interesting inner life too.
We have comets and asteroids to thank for Earth’s water, according to the most widely-held theory among scientists. But it’s not that cut-and-dried. It’s still a bit of a mystery, and a new study suggests that not all of Earth’s water was delivered to our planet that way.
According to Musk’s latest update, SpaceX will be conducting a test flight of their BFR system next year using a miniature version of the spacecraft.
Thanks to a team from John Hopkins University, a star was recently discovered that is 13.5 billion years old, almost as old as the Universe itself! The post Ancient Star Found that’s Only Slightly Younger than the Universe Itself appeared first on Universe Today .
After careful consideration, NASA has selected the location where the InSight lander will set down and begin surveying the interior of Mars The post Mars InSight Lands on November 26th.
That stunning rectangular iceberg that was photographed in mid-October by NASA scientist Jeremy Harbeck had a much more harrowing journey than we thought. Scientists looked back through satellite images to retrace the ‘berg’s journey. They found that it calved from the Larsen C Ice Shelf in November 2017

We Could Build a Powerful Laser and Let Any Civilizations Within 20,000 Light-Years Know We’re Here. Although… Should We?
A powerful laser is just the thing to announce our presence as a technological species in this arm of the galaxy.
Our universe is capable of some truly frightening scenarios, and in this case we have an apparent tragedy: two stars, lifelong companions, decide to move away from the Milky Way galaxy together. But after millions of years of adventure into intergalactic space, one star murders and consumes the other
Thanks to the GRAVITY collaboration, astronomers have made the most detailed observations of the black hole at the center of the Milky Way to date. The post Astronomers Get as Close as They Can to Seeing the Black Hole at the Heart of the Milky Way appeared first on Universe Today .
At the fourth Landing Site Workshop in October, NASA held a vote on where the Mars 2020 rover will land once it reaches the Red Planet The post Planetary Scientists Have Chosen a Few Landing Sites for the Mars 2020 Rover appeared first on Universe Today .
A new study from the Harvard-Smithsonian Center for Astrophysics indicates that exoplanets with too much water or too much landmass may not be a good place to look for life. The post Exoplanets Will Need Both Continents and Oceans to Form Complex Life appeared first on Universe Today
To really study something, you want to reach out and touch it. But what can you do if you’re separated by a huge distance
The ESO has broken ground on the Extremely Large Telescope, which will be the world’s largest and most-advanced telescope once it is complete in 2024. The post An Extremely Large Hole has Been Dug for the Extremely Large Telescope appeared first on Universe Today .
Supernovae are the granddaddies of all cosmic light shows, and Supernova 1987a is one of the most studied objects in the history of astronomy. As its name makes clear, it was first observed in 1987, and it’s the closest supernova observed since the telescope was invented.

It’s Over For Kepler. The Most Successful Planet Hunter Ever Built is Finally out of Fuel and Has Just Been Shut Down.
After eight years of service and thousands of exoplanet discoveries, the Kepler space telescope has run out of fuel and will be retired.
Nothing lasts forever, especially an iceberg drifting away from its frigid home. This coffin-shaped iceberg was spotted by astronauts on the International Space Station as it drifted northwards. It split off from a much larger iceberg about 18 years ago, and is moving into warmer and warmer waters.
