The Hubble Telescope Has Measured a White Dwarf Mass for the First Time
Astronomers have directly measured the mass of a lone white dwarf for the first time using the Hubble Space Telescope. The dwarf, named LAWD 37, is about a billion years old and is 56% the mass of our Sun. With this information, astronomers will be able to test the relationship between mass and radius for other white dwarfs, in turn revealing more information about how matter works under such extreme gravitational conditions.
Here's How Paris Will Keep Athletes Cool Using Clean Energy During the 2024 Olympics
The organizers of the 2024 Paris Olympics have come up with an innovative way to keep athletes cool during the summer without relying on air conditioners. They plan to use an underground water cooling system beneath the Athletes Village instead. This sustainable method uses the same technology that kept the iconic Louvre museum cool during last summer’s heat waves. This method will lower carbon impact for the Olympic Athletes Village by about 45%. The Paris organizers hope to set an example for future Olympics to prioritize the environment.
These Students Created a 3D Printed Prosthetic Leg For Their Teacher's Dog
A group of high school students from Charlotte, North Carolina have created a 3D-printed prosthetic limb for their teacher’s golden retriever, Bentley, after he lost his leg to cancer. The students used the school’s 3D imaging equipment to design a harness attached to a prosthetic limb for Bentley. They were thrilled to see their invention improve the life of Bentley, who took to his new limb with ease. Ashley Liberto, Bentley's owner and teacher of the students, was proud of her students' innovation and said they "want to do big things in life."
Don't Miss It: Jupiter and the Moon Will Meet in the Night Sky Tonight
Get ready for an exciting celestial event tonight! The moon and Jupiter are going on a special date, and they're sharing the same right ascension, which is called a conjunction. You can see this in the night sky as they make a close approach, known as an appulse. Although the two will appear close in the sky, Jupiter is over 2,000 times farther from Earth than the moon! While they won't be visible in a telescope, a pair of binoculars will do the trick. If you snap a photo, you can share it with Space.com's readers. Happy stargazing!

Germany is Rising Up to Meet the Solar Power Demand With a New School
Germany is on a mission to become carbon neutral and solar power is a key component of that plan. To meet the soaring demand for solar power, Berlin start-up Enpal has started its own vocational school to train people from all backgrounds to become solar panel installers and specialized electricians. With the German solar industry experiencing a significant shortage of qualified workers, Enpal's training school is helping to bridge the gap and provide opportunities for people to learn new skills and contribute to the country's energy transition.
A New 3D Microscope Can Capture Life in Unprecedented Detail
Graduate students at Duke University have created a microscope that can see 'like human vision.' Researchers used 24 smartphone cameras to stitch together gigapixel images over an area about the size of a piece of paper. The microscope is capable of recording 3D movies of the behavior of freely swimming zebrafish or the activity of fruit flies at near cellular-level detail across a wide field of view, allowing new discoveries in the field of biology. Six years in the making, the Multi Camera Array Microscope is opening new possibilities to researchers.
Cancer Patients Now Have Inclusive Wig Options Thanks to Two Sisters
