For most art-world buyers, a work unsubtly called “Comedian” lacked a certain a-peel. But on Wednesday, Cattelan got the last laugh as “Comedian” sold for $6.24 million, including $1 million in fees. The buyer was soon revealed to be Justin Sun, a 34-year old cryptocurrency platform founder from China and based in Switzerland. And while some who have capitalized on those assets will inevitably purchase art, artworks themselves have their own rates of return that depend more on evolutions in taste that don’t correlate with wider macroeconomic trends. Sun, the “Comedian” buyer, used his own cryptocurrency, TRX, to make the purchase, Sotheby’s said.

Voyager 1 is now using a radio transmitter it hasn’t relied on since 1981 to stay in contact with its team on Earth while engineers work to understand what went wrong. NASA's Voyager 1 spacecraft is depicted in this artist's concept traveling through interstellar space, or the space between stars, which it entered in 2012. Voyager 1 has been using one of its two radio transmitters, called an X-band based on the frequency it utilizes, for decades. In the meantime, engineers sent a message to Voyager 1 on October 22 to check that the S-band transmitter was working and received confirmation on October 24. “The S-band signal is too weak to use long term,” Waggoner said.

But if the storm escalates to a G5, auroras could be visible across southern states and elsewhere around the world.

The silvery orb is near or at the farthest point in its orbit from our planet, so it can’t completely block the sun as it does during a total solar eclipse. Another annular solar eclipse will arrive on February 17, 2026. Finally, a total solar eclipse — such as the one that drew millions of spectators across North America last April — will once again grace the skies on August 12, 2026. To witness any of these solar eclipse events, be sure to use certified eclipse glasses or a handheld solar viewer to shield your eyes from the sun’s harmful rays and observe the event safely. But don’t look through any optical device — camera lens, telescope, binoculars — while wearing eclipse glasses or using a handheld solar viewer, according to NASA.

☆ NASA powers off a piece of Voyager 2 science to save power
▼ + stars: | 2024-10-02 | by ( Jackie Wattles | ) edition.cnn.com time to read: +2 min

CNN —The NASA team overseeing the iconic Voyager 2 spacecraft made the decision to power down one of its science instruments in an effort to conserve energy. Despite the aging probe’s emptying power stores, NASA expects that Voyager 2 will keep operating with at least one science instrument into the 2030s. Voyager 2 has three radioisotope thermoelectric generators that power the spacecraft by converting heat emitted by the decaying plutonium into electricity. But turning off a piece of equipment on Voyager 2 or Voyager 1 — an identical spacecraft launched 16 days after its twin — is not ideal, NASA noted. After reaching beyond the heliosphere, or interstellar space, Voyager 2 has “collected limited data in recent years due to its orientation relative to the direction that plasma is flowing,” NASA said.

Currently the farthest spacecraft from Earth, Voyager 1 is about 15 billion miles (24 billion kilometers) away. Earlier this year, engineers spotted an issue when the fuel tube inside one of Voyager’s thrusters became clogged. Engineers switched again to the trajectory correction thruster set in 2018 when the second set also appeared clogged. Once the spacecraft has exhausted this thruster set, Voyager 1’s remaining option is the other already clogged set of attitude propulsion thrusters.

☆ Opinion | The Risks of Experimenting With the Sun
▼ + stars: | 2024-08-13 | by ( ) www.nytimes.com time to read: +1 min

Claims that solar radiation modification, or S.R.M., could control the sun’s warming effects ignore the immense risks and the reality of sudden temperature spikes if deployment is stopped. This technology could never “restore” the climate but would further destabilize an already disturbed climate system, leading to unforeseen and irreversible ecological disasters, and severely affecting current and future generations. Almost 500 leading scientists and more than 2,000 civil society organizations worldwide are calling for a solar geoengineering non-use agreement. Both African ministers and the European Parliament have called for such a mechanism, reflecting a growing consensus against these dangerous experiments. It’s alarming that the key lesson learned from the Harvard solar geoengineering research project’s failure appears to be to proceed with less transparency, denying the public’s right to know about future experiments — while ignoring a global de facto moratorium of the United Nations on all geoengineering.
