More space beauty for your day: This new @NASAWebb image of Uranus shows exquisite detail in the rings, clouds, and huge polar cap. Imagine what it took to knock this planet on its side. Processing by Andrea Luck. https://t.co/QBgjv6muMB

What a strange, beautiful shot of Comet Lemmon, now passing through the northwest sky after sunset. Here you see two comet tails (gas and dust), plus the unrelated zigzag trail of a passing meteor. And, inevitably, a couple satellite trails, too. https://t.co/ItaQ1azfyw

Possible wind speeds in excess of 190 miles per hour for Hurricane Melissa. We are in unprecedented territory.

Melissa now at T8.3. Hard to know what's truly under the hood without aircraft reconnaissance right now but satellite says surely this is a Category 5. Regardless, we're witnessing satellite history in the Atlantic tonight.

@brighter_news @CNSA_en Early results from Chang'e-6 indicate late-period volcanism on the Moon & deepen the mystery of why the Moon's farside looks so different from the side we see. The lander also gathered this beautiful & intriguing collection of lunar impact glass beads. https://t.co/3GU8UzaMjR

Chang'e-6 was a complex mission that landed on the lunar farside, communicated via relay satellite, and returned the first samples from the other side of the Moon. A sign of things to come: China has many more groundbreaking space missions in the works. https://t.co/ogAZYzIeoX

China's Chang'e-6 sample-return mission discovered that the far side of the Moon is covered with fragments of carbonaceous, water-rich meteorites. Long ago, similar objects may have helped give Earth its oceans & delivered raw materials for life. https://t.co/y6Qw6BY2G6

A mole is the number of atoms in a gram-molecular weight of an element/compound--eg, the number of atoms in 12 grams of carbon-12. It tells you how many atoms there are in the world. 1 mole is about 6 x 10^23, hence 10/23 being Mole Day. (It rounds closer to 10^24. Whatevs.)

We already knew that planets can survive after a sunlike star dies & fades away as white dwarf. But it's surprising to see the system still in chaos billions of years later. This star recently ate a large asteroid or planetary fragment. Paper at link. https://t.co/etogjKiJVH

Astronomers have determined that an aging white dwarf star, 3 billion years into its final stage of life, is still busily crushing and devouring its planets. Scientific data on the left. Artist's interpretation on the right. https://t.co/LNLIFyGcnz

@brighter_news Strictly speaking, this isn't the first time we've observed the formation of a new system of rings in space. Over the past half century, we clever humans have created our own set of rings around Earth. https://t.co/vSdrqQ9G8Q

Chiron is a 200 km oddity orbiting the Sun between Saturn & Uranus. Its rings may have formed from an impact, a broken satellite, or eruptions from Chiron itself. Here's a more accessible story about the young, fast-changing rings around Chiron: https://t.co/jQc0KUQshl

Astronomers have discovered rings forming around a Centaur. For real: Chiron (a comet-asteroid hybrid orbiting beyond Saturn) has set of rings that seem to be changing by the year. Regardless of what's happening on Earth, space continues to be amazing. https://t.co/dI6oMolthD

Something big is happening 2,000 miles underground, where Earth's inner ocean of molten iron generates the global magnetic field. The strong parts of the field near the poles are changing, too, getting weaker over Canada and stronger over Siberia. https://t.co/0HoTb6MS2k

Earth's magnetic field is changing, with its weak spot (the South Atlantic Anomaly) growing significantly over the past decade. No, it's not doomsday, but it does affect the radiation doses hitting satellite that pass through that region. https://t.co/0HoTb6MS2k

The universe used to seem less lonely. Into the 19th century, scientists commonly speculated about intelligent life on Mars, Venus & the Moon. William Herschel, the century's greatest observer, even suggested there might be life on the Sun! https://t.co/46j2cwi7eX

More information about United Airlines flight 1093, which was struck by something at 36,000 feet. The captain speculated it was falling space debris (natural or human). But extreme-altitude hail might also be possible. https://t.co/QHeeQO5xFU

Wild! A meteorite may have struck the windshield of a 737 flying over Colorado, according to early reports. Whatever the object was, it cut a pilot's arm but did not seriously damage the plane. https://t.co/78Sa6l7Dtj
