Mars weather: Clear with a low of 114 below zero

NASA's Curiosity rover has been roaming the Red Planet since 2012, taking thousands of pictures, drilling small holes in the planet's surface and searching for evidence of past habitable environments on Mars. It has also been busy observing the weather.
Curiosity is outfitted with a miniature weather station that measures temperature, humidity, winds, pressure and ultraviolet radiation. These observations are sent back to Earth on a regular basis, and they help scientists understand the alien weather on the desolate world.
On May 12, the high temperature was 11 degrees below zero, and the low temperature was a staggering 114 degrees below zero.

It is currently late autumn in Gale Crater, the region of Mars where Curiosity is exploring, meaning even colder weather is ahead for the rover in the coming months.
Temperatures on Mars can climb as high as 70 degrees during the summer months and as low as 225 degrees below zero during the coldest winter nights. And there can even be dramatic changes in temperature across just a few feet.
"Because the atmosphere is so thin, heat from the Sun easily escapes this planet," NASA explained. "If you were to stand on the surface of Mars on the equator at noon, it would feel like spring at your feet and winter at your head."
NASA has also documented Earth-like weather phenomena, including dust devils and shimmering clouds.

With 'Atmosphere,' Taylor Jenkins Reid leaves the Evelyn Hugo-verse behind and travels to space
Taylor Jenkins Reid recalls a moment writing her new novel, 'Atmosphere: A Love Story,' set against NASA's robust 1980s shuttle program, where she felt stuck. She went, where she often goes, to her husband to talk it through. 'I said, 'I can't write this book. I don't know enough about the space shuttle. I don't know what happens when the payload bay doors won't shut and you have to get back within a certain amount of revs, but they can't land at White Sands. They have to land at Cape Kennedy.' And he's like, 'Just listen to yourself. You know so much more than you knew a couple months ago. Keep doing what you're doing.''

Bright green meteor zooms past Sydney as auroras dazzle across Australia
A bright green meteor was seen zooming past Sydney on Sunday as spectacular southern lights lit up the skies across most of Australia and New Zealand. A Sydney resident named Tom McCallister posted a video of the meteor, about the size of a basketball, traversing the city's skies. 'Absolutely magnificent meteor seen travelling east to west over Sydney this evening,' Mr McCallister captioned the video posted on Facebook. 'This was looking north at 17:57 local time.' Astrophysicist Brad Tucker, from the Australian National University, agreed that the object was indeed a meteor due to its unique blue-green colour, indicative of iron and nickel content. Anyone else just see a green, long meteor over Canberra? Tried to get a photo but I've only got slow shutter speeds on - out waiting for Aurora Australis instead - but that's a good start to the night! — Nat (@raurkyn) June 1, 2025 People across New Zealand and on Australia's east coast were also treated to a dazzling display of southern lights on Sunday. Many skygazers later shared photos of aurora australis on social media. The space weather phenomenon is caused when bursts of charged particles released from the Sun – known as coronal mass ejections, or CMEs – interact with the Earth's magnetic field, creating what's called a geomagnetic storm. The lights are called aurora australis in the southern hemisphere and aurora borealis in the northern hemisphere. Pictures posted on social media showed the sky glowing in hues of pink, red and green, with slight traces of yellow. The colours come from different molecules in the atmosphere getting charged by the Earth's magnetic field. Oxygen gives off a fluorescent green hue while nitrogen molecules interacting with the magnetic field generate a blue, red or pink shade. Auroras are seen when a strong solar storm from the Sun hits the Earth. They are more clearly visible around polar regions since the magnetic field is the strongest there. Aurora Australis dancing over Merimbula Lake in NSW, Australia this evening. — Fiona Brook (@The_Feefenator) June 1, 2025 Astronomers have predicted a strong geomagnetic storm on Sunday and Monday after a powerful CME was seen erupting from the Sun on Friday. The latest CME also caused aurora borealis across most of the continental US as far down south as Alabama. The US National Oceanic and Atmospheric Administration said the possibility of a severe geomagnetic storm remained 'in effect'. 'There are indications that the coronal mass ejection passage is weakening, but the solar wind conditions remain elevated, therefore additional periods of G3-G4 levels remain possible,' the NOAA said, using the designations for strong and severe category storms. 'However, we now anticipate that conditions should weaken enough by tomorrow evening, 2 June, that G1 storm levels are the most likely peak response.' The Sun is currently at the peak of its 11-year activity cycle.

A chance to spot rare and mysterious noctilucent clouds
It's time to watch for the beautiful cloud formations known as noctilucent clouds. Latin for 'night shining', noctilucent clouds are seasonal and become visible in the northern hemisphere from late spring/early summer. Although unpredictable, when they do appear they will be seen in the western sky about half an hour after the sun sets. As the sky darkens into night, they will shine with an extraordinary electric blue colour. Part of the appeal of these rare clouds is that their origins are still mysterious. They are the highest known clouds in Earth's atmosphere, condensing at an altitude of about 80km (50 miles). This is virtually the edge of space. Their extreme altitude is what allows them to catch the last rays of the setting sun, even when Earth's surface beneath them is already in darkness. Perhaps the most puzzling aspect of the clouds is that there are no recorded sightings of them before 1885. Some suggest the clouds are therefore caused by industrial pollutants to which water vapour freezes, or by the rise of the greenhouse gas methane in the atmosphere, which promotes water vapour production in the upper atmosphere. In the southern hemisphere, the noctilucent cloud season begins around October.
