Five years after NASA’s MAVEN spacecraft entered into orbit around Mars, data from the mission has led to the creation of a map of electric current systems in the Martian atmosphere.
“These currents play a fundamental role in the atmospheric…

The asteroid that killed the Dinosaurs stuck earth at ‘deadliest possible’ angle
Simulations to recreate the extinction-level event that killed 75% of life on Earth 66 million years ago, has shown the angle the asteroid struck was at 60 degrees.
At this angle it maximised the amount of climate-changing gases thrust into the…

Charging orbital fees to solve the problem of space junk in orbit
The orbit around the earth is becoming crowded with aging satellites and space debris that presents a risk of collision with every new launch.
The most effective way to solve the space junk problem, according to a new study, is not to capture…

Astronomers see ‘cosmic ring of fire,’ 11 billion years ago
Astronomers have captured an image of a super-rare type of galaxy – described as a “cosmic ring of fire” – as it existed 11 billion years ago.
The galaxy, which has roughly the mass of the Milky Way, is circular with a hole in the middle,…

Using Drones to Monitor Explosive Volcanoes
Due to the difficult accessibility and the high risk of collapse or explosion, the imaging of active volcanoes has so far been a great challenge in volcanology.
Researchers around Edgar Zorn from the German Research Centre for Geosciences GFZ in…

Higher Sea Level Rise Predicted by Melting Ice Sheets
A new study by the Nanyang Technological University has been studying melting polar ice sheets and predicts that ocean levels will rise by as much as 1.3 metres by 2100.
The new study makes sea-level rise projections which are significantly…

The lower mantle can be oxidized in the presence of water
If we took a journey from Earth’s surface to the center, the midway point locates roughly at 1900 km depth in the lower mantle.
The lower mantle ranges from 660 to 2900 km depth and occupies 55% of our planet by volume. The chemical composition…

ALMA spots twinkling heart of Milky Way
Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) found quasi-periodic flickers in millimeter-waves from the center of the Milky Way, Sagittarius (Sgr) A*.
The team interpreted these blinks to be due to the rotation of…
