A team of astronomers led by Carnegie’s Scott S. Sheppard have recently found 20 new moons around Saturn These new moons bring the total number to 82, which makes Saturn the mooniest planet in the solar system. What’s more, you can help name the new ones!
Matteo Ceriotti, University of Glasgow In the Chinese science fiction film The Wandering Earth, recently released on Netflix, humanity attempts to change the Earth’s orbit using enormous thrusters in order to escape the expanding sun – and prevent a collision with Jupiter. The scenario may one day come true. In five billion years, the sun […]
After ʻOumuamua, now we are likely to have another interstellar visitor beyond our solar system: comet C/2019 Q4 (Borisov). So the interstellar objects entering the solar system may not be rare at all.
On June 20, 2019, Hubble Space Telescope snapped this beautiful portrait of Saturn and its rings at the ringed planet’s closest approach to Earth. The image was published on September 12, 2019.
To see exactly where the spacecraft and the celestial bodies (planets and other astronomical objects) really are, right now, you can use NASA’s real-time, 3D solar system model.
Now we’re living on a warm, hospitable planet. As Carl Sagan has said “That’s home. That’s us. On it everyone you love, everyone you know, everyone you ever heard of, every human being who ever was, lived out their lives.” We, humans, are the unquestionable rulers of our little oasis in a hostile universe. But […]
Hubble Space Telescope was launched on April 24, 1990, and entered service on May 20, 1990. Since then, it has observed all the planets in our Solar System, apart from Earth and Mercury. Earth is far better studied by geologists on the ground and specialized probes in orbit. Hubble can’t observe Mercury as it is […]
Jupiter’s moon Ganymede is the largest and most massive of the Solar System’s moons. It has a mean radius of 2634.1±0.3 km (about 1636 miles, 0.413 Earths). For comparison, our Moon’s radius is 1,737.1 km (1079 mi). What if Ganymede was the Earth’s second moon? How would it look in the sky, if it was […]
Earth, our blue planet is a tiny oasis in the vast, cold, and dark space. It is the only planet we know of that can support life. The fossil record tells us that life on Earth has lasted at least 3.5 billion years (the Earth is about 4.54 billion years old), with the oldest physical […]
Another “putting things into perspective” video which I liked, showing how big space is, and actually how far the nearest stars from us.
