Meteor shower to peak today: Here's when and the best way to watch, Credit: Pixabay/CC0 Public Domain One of the oldest known meteor showers is streaking through the sky above California. The Lyrid meteor shower was first recorded in 687 B.C. and has been studied for more than 2,000 years, according to NASA. The meteor shower occurs every April, peaking this year on April 22. Question: What is a meteor? Answer: Meteors are essentially debris in the sky. They come from leftover comets and broken asteroids,

Per NASA: View the Sun through eclipse glasses or a handheld solar viewer during the partial eclipse phases before and after totality. You can view the eclipse directly without proper eye protection only when the Moon completely obscures the Sun’s bright face – during the brief and spectacular period known as totality. (You’ll know it’s safe when you can no longer see any part of the Sun through eclipse glasses or a solar viewer.) As soon as you see even a little bit of the bright Sun reappear after totality, immediately put your eclipse glasses back on or use a handheld solar viewer to look at the Sun.

NASA - National Aeronautics and Space Administration Manicouagan Impact Crater from Space (APOD: 2024 May 25) Image Credit: NASA, International Space Station Expedition 59 https://lnkd.in/gAh_Qey6 Explanation: Orbiting 400 kilometers above Quebec, Canada, planet Earth, the International Space Station Expedition 59 crew captured this snapshot of the broad St. Lawrence River and curiously circular Lake Manicouagan on April 11. Right of center, the ring-shaped lake is a modern reservoir within the eroded remnant of an ancient 100 kilometer diameter impact crater. The ancient crater is very conspicuous from orbit, a visible reminder that Earth is vulnerable to rocks from space. Over 200 million years old, the Manicouagan crater was likely caused by the impact of a rocky body about 5 kilometers in diameter. Currently, there is no known asteroid with a significant probability of impacting Earth in the next century. Each month, NASA’s Planetary Defense Coordination Office releases an update featuring the most recent figures on near-Earth object close approaches, and other facts about comets and asteroids that could pose a potential impact hazard with Earth. https://www.nasa.gov/ https://lnkd.in/gpEUJiup Starship Asterisk* • APOD Discussion Page https://lnkd.in/g3ipZaXs #APOD #EarthOrbit #Space #EarthObservations #NASA #ISS #internationalspacestation #astronauts #Science #Laboratory #NearEarthObjects #Tracking #

Ice Clouds over a Red Planet Image Credit: NASA, JPL-Caltech, Kevin M. Gill; Processing: Rogelio Bernal Andreo Explanation: If you could stand on Mars -- what might you see? You might look out over a vast orange landscape covered with rocks under a dusty orange sky, with a blue-tinted Sun setting over the horizon, and odd-shaped water clouds hovering high overhead. This was just the view captured last March by NASA's rolling explorer, Perseverance. The orange coloring is caused by rusted iron in the Martian dirt, some of which is small enough to be swept up by winds into the atmosphere. The blue tint near the setting Sun is caused by blue light being preferentially scattered out from the Sun by the floating dust. The light-colored clouds on the right are likely composed of water-ice and appear high in the Martian atmosphere. The shapes of some of these clouds are unusual for Earth and remain a topic of research. #PhoenixDelivers #nasa

A total solar eclipse crosses North America on April 8, 2024, with parts of 15 U.S. states within the path of totality. Maps show where and when astronomy fans can see the big event. The total eclipse will first appear along Mexico's Pacific Coast at around 11:07 a.m. PDT, then travel across a swath of the U.S., from Texas to Maine, and into Canada. About 31.6 million people live in the path of totality, the area where the moon will fully block out the sun, according to NASA. The path will range between 108 and 122 miles wide. An additional 150 million people live within 200 miles of the path of totality.

🌌 Unveiling Secrets of the Cosmos: NASA's Historic Sample Return from Asteroid Bennu! 🚀 On September 24, 2023, we witnessed a monumental achievement in space exploration: NASA's OSIRISEx mission successfully returned samples from the near-Earth asteroid Bennu after a seven-year journey! 🌍🔬 Why is this significant? Here’s what these samples mean for us: Invaluable insights: The pristine material collected from Bennu helps us understand the early solar system’s formation. Understanding planetary building blocks: These samples could be key in deciphering the origins of planets. Asteroid impact insights: Research from this data may reveal potential threats from similar asteroids in our future. Asteroids like Bennu are considered "primitive," providing a unique opportunity to study materials that have remained largely unchanged for billions of years. This expedition propels our knowledge and paves the way for future discoveries! 🌠💡 Let’s celebrate this incredible leap in science together! What are your thoughts on space exploration and its impact on our understanding of the universe? #NASA #SpaceExploration #Science #Asteroids #Bennu #OSIRISREx #STEM #Innovation #SpaceScience #SampleReturn #SolarSystem

Phobos: Moon over Mars Image Credit: NASA, ESA, Zolt Levay (STScI) - Acknowledgment: J.Bell (ASU) and M.Wolff (SSI) Explanation: A tiny moon with a scary name, Phobos emerges from behind the Red Planet in this timelapse sequence from the Earth-orbiting Hubble Space Telescope. Over 22 minutes the 13 separate exposures were captured near the 2016 closest approach of Mars to planet Earth. Martians have to look to the west to watch Phobos rise, though. The small moon is closer to its parent planet than any other moon in the Solar System, about 3,700 miles (6,000 kilometers) above the Martian surface. It completes one orbit in just 7 hours and 39 minutes. That's faster than a Mars rotation, which corresponds to about 24 hours and 40 minutes. So on Mars, Phobos can be seen to rise above the western horizon 3 times a day. Still, Phobos is doomed. #PhoenixDelivers #nasa

Planet Saturn: 18-hours of Moon Motion Observations: August 2024 | Hubble. This is a time-lapse video of a Hubble Space Telescope set of images taken of planet Saturn in August 2024. In the 18 hours of observations several small icy moons are visible in every frame speeding around like race cars: Dione, Enceladus, Janus, Mimas, and Tethys. Their orbits are co-planar with Saturn's magnificent rings. Dusty "spokes" in the rings can also be seen rotating around the planet in this movie. These images were taken under a Hubble program called Outer Planet Atmospheres Legacy (OPAL). ٓ Credits: Science: NASA, European Space Agency, Amy Simon (NASA-GSFC), Michael H.
