Today is the last day of the 2010s – and what a decade it has been for space science and space exploration! Here is a timeline of the top 20 major (and exciting!) advances in space science in the 2010s.
Christopher Palma, Pennsylvania State University As an astronomer, the question I hear the most is why isn’t Pluto a planet anymore? More than 10 years ago, astronomers famously voted to change Pluto’s classification. But the question still comes up.
On October 18, 2019, NASA held an AMA (Ask Me Anything) on Reddit. Scientists from the space agency answered questions about Van Allen Probes, two robotic spacecraft that were used to study the Van Allen radiation belts that surround planet Earth.
Did you know that the Moon and space itself have a smell? Space has a lot of surprises. Here are the 10 lesser-known space facts.
We can turn Earth into a giant telescope. According to a recent study titled “The ‘Terrascope’: On the Possibility of Using the Earth as an Atmospheric Lens”, published by David Kipping of Columbia University, our planet offers an opportunity for pronounced lensing.
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 […]
This amazing photo of the 2019 Solar Eclipse from the Moon’s orbit was taken on July 2, 2019, by the Chinese lunar satellite DSLWP-B (Longjiang-2).
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.
Melodysheep published an amazing video titled “Timelapse of the future: a journey to the end of time”. This experience takes us on a journey to the end of time, trillions of trillions of years into the future, to discover what the fate of our planet, our sun, and our universe may ultimately be. If this […]
