Galaxies are not static islands of stars — they are dynamic and ever-changing, constantly on the move through the darkness of the Universe. Sometimes, as seen in this spectacular Hubble image of Arp 256, galaxies can collide in a crash of cosmic proportions.
New data from the Atacama Large Millimeter/submillimeter Array (ALMA) and the IRAM 30-m telescope have been used to create one of the largest high-resolution mosaics of a star formation region produced so far at millimeter wavelengths.
Data collected by NASA’s Juno mission to Jupiter indicate that the atmospheric winds of the gas-giant planet run deep into its atmosphere and last longer than similar atmospheric processes found here on Earth. The findings will improve understanding of Jupiter’s interior structure, core mass and, eventually, its origin.
Futurist Michio Kaku sees humans doing ballet on Mars and projecting their brains into the cosmos. And aliens? Oh, they’re coming.
At the time of the Big Bang, all the matter in the universe was smooshed into an incredibly hot, infinitely dense speck of matter.
A new explanation for the moon’s origin suggests it actually formed inside our Earth – when our planet was still a seething, spinning cloud of rock, shaped like a doughnut. Previously, scientists believed that the moon formed as a result of a glancing blow between the early Earth and a Mars-size body, commonly called Theia.
Cosmic rays are bad–and they’re getting worse. That’s the conclusion of a new paper just published in the research journal Space Weather.
A team of planetary scientists from Brown University and NASA’s Goddard Space Flight Center has mapped the mineralogy of the South Pole-Aitken basin, a vast impact structure on the far side of the Moon. Published in the Journal of Geophysical Research: Planets, the findings could help guide future exploration of the basin.
When you look up at the moon, it’s hard to believe this mystical glowing orb floating among the stars was once in the throes of chaos.
NASA has said a newly-discovered space rock as big as a three-storey house is on an “uncertain” path with our planet – so will Asteroid 2018 AJ hit Earth?
