Hubble breaks cosmic distance record
Astronomers have shattered the cosmic distance record by measuring the distance to the most remote galaxy ever seen in the Universe -- a stellar city that existed just 400 million years after the big bang 13.8 billion years ago. The amazing discovery was achieved by pushing the Hubble Space Telescope to its absolute limits.
Scientists watch the Moon breath
Researchers have watched the Moon's tenuous atmosphere -- known as an exosphere -- change depending on its exposure to the Sun and to meteor showers. The findings help astronomers better understand the physics of exospheres which are one of the most dominate types of atmospheres in the solar system.
How Mars got its tilt
A new study claims the surface of Mars was dramatically tilted around 3 to 3.5 billion years ago by a massive volcanic structure known as the Tharsis dome, which is the largest in the Solar System. Because of its extraordinary mass, the Tharsis dome caused the red planet’s crust and mantle to rotate around its core. The discovery of this huge shift changes our vision of Mars during the first billion years of its history, at a time when life may have emerged on the red planet.
SpaceX finally flies on its fifth attempt
After five launch attempts spanning almost two weeks a SpaceX Falcon 9 rocket has finally blasted off from the Cape Canaveral Air Force base in Florida, carrying the SES-9 telecommunication satellite into orbit. The Falcon 9 trailed a golden orange plume as it flew over the Atlantic Ocean carrying its Boeing built satellite into geostationary orbit.
