Seismic Missions Could Reveal the Solar System's Underworlds - Scientific American

Besides their successful landing on the moon, the astronauts of Apollo 11 made another historic “first” in July 1969 when Buzz Aldrin radioed a message back to Earth: “Houston, the passive seismometer has been deployed manually.

“This has the potential to be the beginning of a new golden age” in which scientists will peel back the layers on moons and planets alike to glimpse their hidden innards, says Mark Panning, a planetary seismologist at NASA’s Jet Propulsion Laboratory (JPL).

Order Of Planets In The Solar System

Nation World News – The Solar System extends from the Sun, called Sol by the ancient Romans, and through the four inner planets, through the asteroid belt to the four gas giants and into the disk-shaped Kuiper Belt and the teardrop-shaped heliopause Goes far away. ,

Scientists estimate that the edge of the Solar System is about 9 billion miles (15 billion kilometers) away from the Sun. Beyond the heliopause is the huge circular Oort Cloud, which is believed to surround the Solar System.

PennWest Edinboro hosts astronomy camp for students with visual impairments

Dr. David Hurd, director of Edinboro's planeterium, works with Emma Pabrazinsky, of Johnstown, Pa., and YiLi Smedley, from Titusville, Pa., during the Summer Astronomy Camp for Blind and Visually Impaired High School Students.

The last total solar eclipse that was clearly visible from North America occurred in August 2017. The next major eclipse will pass over Edinboro on April 8, 2024, as the community lies within the path of totality – where the moon covers the sun completely.

Inside the hunt for mysterious 'twilight' asteroids | National Geographic

A mysterious group of asteroids grazes the heart of the solar system, hiding in sunlight and occasionally swooping close to a rocky planet.

Astronomers estimate they've found the majority of the potentially hazardous asteroids that mainly exist beyond our home world's orbit.

"They spend a lot of their time interior to the Earth, but a lot of them can cross–and will cross–Earth's orbit, which makes them dangerous," says Scott Sheppard , an astronomer at the Carnegie Institution for Science who recently wrote an article about these asteroids in the journal  ...

Is China really plotting to take over the moon?

First, we can dispense with any protestations on behalf of the CCP of high-mindedness concerning its space program. China has been fortifying islands in the South China Sea.

Mining lunar resources and transporting them back to Earth or to orbital factories would be a formidable task. However, companies such as SpaceX and Rocket Lab have reduced the cost of space flight.
