This simple failure illustrates a profound headache in space exploration: tools designed for terrestrial use often become useless in a microgravity environment. Robots, for all their technological sophistication, are no exception. Autonomous free-flying robots aboard the International Space Station (ISS) frequently lose their bearings. Without gravity to distinguish up from down, even precision sensors suffer from accumulating errors, causing the machines to drift. Until recently, astronauts sometimes had to intervene…
Just about any monitor can work with a Mac Mini. It doesn’t need to be made by Apple or have any official certification. There’s a case to be made for using a cheap 1080p monitor with the Mac Mini, but most Mac users will want something a bit more premium. As you can see by options like the Dell 27 Plus 4K, that doesn’t have to mean overly expensive. Either way, here are the four elements to consider when shopping for a good monitor to go with your Mac Mini.Size and resolution: 27-inch and 32-inch monitors are the most common…
Apple just came out with these M5 MacBook Pro models a few weeks ago and they’re still full price on Apple’s website, but Amazon decided to spread some holiday cheer by lowering the prices on all models to all-time lows. The 24GB/1TB model now costs $1,799 instead of $1,999, and the 16GB/512GB model now costs $1,349 instead of $1,599. This means that these M5 machines are actually cheaper than the M4 generation was when it first came out. You get here Apple’s new M5 chip, a stunning 14.2-inch Liquid display that can reach 1600 nits of brightness and a battery…
Frequently Asked QuestionsAre Large Heaters More Powerful Than Small Ones?AccordionItemContainerButtonNope! It may seem counterintuitive, but large heaters don’t necessarily heat any better than small ones.Whatever their physical size, most space heaters in the US and Canada deliver about the same amount of heat. Space heaters top out at 1,500 watts, which is the highest safe operating load for a 15-amp household circuit. And aside from some low-power personal heaters here and there, most space heaters you’ll find on the market are 1,500-watt heaters.What’s more, electric space heaters are all pretty much 100 percent efficient in converting that electricity to heat.…
Made in collaboration with NASA, this detailed Lego Technic build is based on the real lunar rover used on the Moon during the Apollo 17 mission in 1972. Astronauts haven’t set foot on the Moon since, so this replica commemorates an important piece of space exploration history.When fully assembled, Lego’s replica of the Lunar Roving Vehicle measures 15 x 10 x 5.5 inches.The bulk of the 1,913 pieces are used to build the large LRV, but this set also has a few modular components that can be detached and displayed separately. One cool aspect with the modular builds is that…
Webb and Chandra spot a cosmic car crash (Image credit: Credit: X-ray: NASA/CXC/SAO; Infrared: NASA/ESA/CSA/STScI/Webb; Image Processing: NASA/CXC/SAO/L. Frattare)QUICK FACTSWhat it is: The spiral galaxies NGC 2207 and IC 2163Where it is: 120 million light-years away, in the constellation Canis MajorWhen it was shared: Dec. 1, 2025A stark new portrait of two colliding spiral galaxies combines different kinds of light to evoke the colors, shapes and moods of autumn. The image, which shows the galaxies NGC 2207 (lower right) and IC 2163 (upper left), was created by combining infrared light captured by the James Webb Space Telescope (JWST) with X-ray…
Similar to the Hobonichi above, the Jibun Techo uses super thin, super soft paper that makes it possible to include all of these pages and books without making it a super-thick planner. I tested the B5 Slim size, which is taller but skinnier than an A5, and I was surprised how happy I was with the space I had for my weekly plans and so much more with all the included pages. I also really like the Ideas book in the back for my never ending lists and notes, and that I could easily swap it out if I filled…
If you peer at the sky during a cloudless dawn or dusk, you’d immediately spot Venus. Appearing as a brilliant, steadily shining speck, it’s the second-brightest object in the night sky after the moon.”The planet is about 100 times brighter than a first magnitude star,” Anthony Mallama, a researcher at the IAU’s Centre for Protection of the Dark and Quiet Sky, told Live Science in an email. First magnitude stars are the brightest stars visible in the night sky. For example, when looking at average brightness, the first magnitude star Sirius is at -1.47, and Venus is at -4.14 (on…
