Hubble Captures Crisp New Image of Jupiter and Europa

heic2017a_0.jpg
This latest image of Jupiter, taken by the NASA/ESA Hubble Space Telescope on 25 August 2020, was captured when the planet was 653 million kilometres from Earth. Hubble’s sharp view is giving researchers an updated weather report on the monster planet’s turbulent atmosphere, including a remarkable new storm brewing, and a cousin of the Great Red Spot changing colour — again. The new image also features Jupiter’s icy moon Europa.

Possible Marker of Life Spotted on Venus

eso2015a_0.jpg
An international team of astronomers announced the discovery of a rare molecule — phosphine — in the clouds of Venus. On Earth, this gas is only made industrially or by microbes that thrive in oxygen-free environments. Astronomers have speculated for decades that high clouds on Venus could offer a home for microbes — floating free of the scorching surface but needing to tolerate very high acidity. The detection of phosphine could point to such extra-terrestrial “aerial” life.

Monitoring the Arctic heatwave

Over the past months, the Arctic has experienced alarmingly high temperatures, extreme wildfires and a significant loss of sea ice. While hot summer weather is not uncommon in the Arctic, the region is warming at two to three times the global average – impacting nature and humanity on a global scale. Observations from space offer a unique opportunity to understand the changes occurring in this remote region.

Patrick Degrosse, engineer at NASA’s Jet Propulsion Laboratory in Southern California, shows the guts of the ventilator that a team of NASA engineers designed in just over five weeks. The machine uses none of the parts used in traditional ventilators, so as not to compete for supply lines.

Hubble Maps Giant Halo Around Andromeda Galaxy

stsci-h-p2046b-m-1999x2000_0.jpg
This illustration depicts the gaseous halo of the Andromeda galaxy if it could be seen with the naked eye. At a distance of 2.5 million light-years, the majestic spiral Andromeda galaxy is so close to us that it appears as a cigar-shaped smudge of light high in the autumn sky. If its gaseous halo could be seen with the naked eye, it would be about three times the width of the Big Dipper—easily the biggest feature on the nighttime sky.
