K2-18b, detected in 2015, orbits a star 124 light years away. Though it is over 800% as large as Earth, its space in the habitable zone of its star, like where we are, means the possibiliy that liquid water could exist on its surface.The science community calls it The Goldilocks Zone. Like the character in the children's story who wanted porridge neither too hot nor too cold, a Goldilocks planet...

That's why the discovery of a star by Hubble 28 billion lightyears away, a new record, may not last long if everything goes as planned with its long-delayed successor, the James Webb Space Telescope....
read moreAbout 23,000,000 years ago, something hit the giant Asteroid 4 Vesta(1) some 120,000,000 miles away and the impact sent huge rocks into space. In 2018, one such meteorite from that time hit Botswana.It was not unique. Over 30 percent of such Howardite-Eucrite-Diogenites (HED) meteorites that hit Earth year come from just the impact that formed the Antonia crater on Vesta. And then there is...
