‘Sprained Ankle’: Opportunity rover sends back new panorama from above ancient gully

NASA’s Opportunity rover has been busy examining the entranceway to Perseverance Valley, a long, shallow gully-like channel on the rim on Endeavour Crater which was likely created by flowing water millions or billions of years ago. This feature has been a major target of interest for mission scientists since, if confirmed, this would be the first such gully seen up close by any rover. A new panoramic image just released shows the view on the crater rim just above the valley itself, which includes a possible “spillway” where water once flowed over the rim and into the crater down below.

Remembering Comet Shoemaker-Levy 9’s impact on Jupiter, 23 years ago this week

Jupiter has been in the news a lot lately, with the Juno spacecraft continuing to send back stunning new images of the largest planet in the Solar System, including close-ups of the Great Red Spot. But something else happened at this time 23 years ago which captured astronomers’ and the public’s attention – a huge explosion in Jupiter’s atmosphere as a comet broke apart and the fragments collided with the planet, plummeting into the deep, thick atmosphere. The impacts and resulting “scars” were observed by telescopes around the world.

What are these weird radio signals from a nearby red dwarf star?

Astronomers are continuing to monitor a nearby red dwarf star after detecting unusual radio signals apparently coming from the star. It is hoped that additional observations will help to determine the source of the signals, which so far haven’t been explained.

Fly over Pluto and Charon for second anniversary of New Horizons’ historic visit

Pluto is a world of wonders, with vast glaciers and plains of nitrogen ice, mountains of water ice capped with methane snow, ancient rivers and lakes of liquid nitrogen, massive “ice spikes” reaching 500 metres tall (similar to Penitentes on Earth but much larger), a possible subsurface ocean and a hazy blue atmosphere.

It was two years ago today that NASA’s New Horizons spacecraft became the first-ever probe to visit Pluto in the cold, outer fringes of the Solar System. To help celebrate the occasion, NASA has posted a new video of the epic flyby, when the spacecraft soared over the tall mountains and vast icy plains of this small but active world.

Juno reveals Solar System’s largest storm like never seen before

Last Monday, July 10, NASA’s Juno spacecraft flew directly over Jupiter’s Great Red Spot for the first time, providing the closest views ever of this gigantic storm system which is much larger than Earth in size. While the science data collected has been streaming back to Earth, what most people have been waiting for of course are the images. The first ones had been expected around Friday this week, but they actually became available yesterday – and as anticipated, they are fantastic!
