When is the next solar eclipse?

NeRD

It’ll be about six months before skywatchers are treated to another solar eclipse — during which only part of the sun will again be obscured from view.  On Oct. 2, an annular solar eclipse was visible from areas in the Southern Hemisphere, including in remote parts of Chile and Argentina. This type of eclipse occurs when the moon passes between Earth and the sun, but does not completely cover the sun’s disk because it is at its farthest point from Earth. Therefore, the moon appears smaller than the sun, creating…

FAA requires investigation of anomaly on SpaceX’s Crew-9 astronaut launch

NeRD

The U.S. Federal Aviation Administration (FAA) is requiring an investigation of the anomaly a SpaceX Falcon 9 rocket experienced during the Crew-9 astronaut launch on Sept. 28. That liftoff successfully sent a Crew Dragon capsule carrying NASA astronaut Nick Hague and Russian cosmonaut Aleksandr Gorbunov toward the International Space Station. However, the Falcon 9‘s upper stage suffered an issue after deploying the capsule, SpaceX revealed on Sept. 29. The issue was an “off-nominal deorbit burn,” which resulted in the upper stage landing in the ocean outside of its target disposal…

China unveils spacesuit for moonwalking astronauts (video)

NeRD

China has strutted out its moon-landing spacesuit, unveiling its design in a ceremony Saturday (Sept. 28) in southwest China’s Chongqing Municipality. A technician put the spacesuit — which China aims to start using on crewed moon missions by 2030 — through its paces, showcasing various movements and gestures, including climbing the rungs of a ladder.  The overall design of the moon-landing suit is inspired by traditional Chinese armor, underscoring the suit’s rugged and resolute appearance. It also features ribbons, which have always been an important element in the design of Chinese…

The Milky Way’s 2 biggest satellite galaxies are oddly lonely, study finds

NeRD

The Milky Way’s system of small, orbiting satellite galaxies is quite unusual, a new 12-year study of other galaxies in the local universe has found.  The Satellites Around Galactic Analogs (SAGA) survey is being conducted by a small group of astronomers to learn how the Milky Way and its little retinue of dwarf satellite galaxies compares to other galaxy systems. “The Milky Way’s satellite population is a unique combination of small satellites containing only older stars, and its two largest satellites, which are actively forming new stars,” says Marla Geha,…

Heart tissues beat half as strongly on the ISS as they do on Earth

NeRD

What effects does spaceflight have on an astronaut’s heart? This is exactly the question that prompted scientists from Johns Hopkins University to send 48 bioengineered heart tissue samples to the International Space Station, where they were monitored for 30 days and compared to identical samples on Earth. The team examined how low gravity impacts things like the cells’ strength of contraction, known as twitch forces, and any irregular beating patterns.  The results were concerning — the scientists found that heart cells “really don’t fare well in space,” beating with about…

Van Gogh’s ‘Starry Night’ surprisingly adheres to the laws of physics, scientists find

NeRD

Vincent van Gogh’s “The Starry Night” is undoubtedly one of the most famous paintings in the world, instantly recognizable for its vibrant colors and dramatic brushstrokes that create what appears to be a sky in motion. But did you know that its night sky depiction actually follows the real laws of physics?  While the scene does take liberty in terms of what our eyes witness in the sky — we don’t necessarily see eddies dancing between the stars — scientists have determined those eddies indeed adhere to the laws of turbulent flow.…

How fast will the annular solar eclipse on Oct. 2 travel?

NeRD

On Oct. 2, an annular solar eclipse will be visible from the Southern Hemisphere. During this event, the moon doesn’t completely cover the sun from our perspective on Earth, so it leaves a “ring of fire” around the moon. The moon’s shadow will appear to travel at vastly different speeds depending on your location. In some places, it will move faster than 6 million mph (10 million km/h); in others, it will travel as slow as 1,278 mph (2,057 km/h), or about the speed of a fighter jet. During the…
