New Images of Mars from the ExoMars Orbiter Features Photo of InSight Lander Seen from Space

The ExoMars Trace Gas Orbiter has taken a wealth of new photographs of the Martian surface, including one showing the InSight lander, which recently touched down on the Red Planet. The images show the great geological diversity of Mars, as well as dunes and evidence of dust devils on the planet. Researchers hope to utilize these photographs during planning for future robotic missions.

Hubble and Gaia Team Up to Measure the Mass of the Milky Way

The mass of the Milky Way Galaxy is a question that has long puzzled astronomers and astrophysicists. Estimates ranged from between 500 billion to three trillion times the mass of our Sun. A new study looked at globular clusters, groupings of a million or so stars surrounding the Milky Way. By measuring the velocity at which they circled our galaxy, as measured by the Hubble Space Telescope and the Gaia Telescope, astronomers determined the Milky Way has a mass around one-and-a-half trillion times as great as our Sun.

Water, Water Everywhere — On Mars?

The Mars Express orbiter has taken photos of river valleys on the Red Planet, showing evidence that liquid water once flowed across the Martian landscape. Once thought to be completely dry, Mars is now known to have water ice beneath its surface, up to 100 meters, or 330 feet, in depth. Billions of years ago, Mars lost most of its atmosphere, and water on its surface disappeared. Astronomers are still uncertain what caused this dramatic climatic change on the Red Planet.

Why Europe is Naming Their Next Mars Rover After Biologist Rosalind Franklin

The European Space Agency announced they are naming their new Mars rover in honor of pioneering biologist Rosalind Franklin. The spacecraft is due for launch in July 2020, and should touch down on Mars in March 2021. The robotic explorer will investigate beneath the Martian crust, looking for evidence of life, past or present, on Mars. Franklin developed groundbreaking research into the study of DNA, work which was used, without credit, by other researchers.
