Hugh Jones, University of Hertfordshire Most exoplanets, bodies orbiting stars other than the sun, are too far away for us to be able to send probes to. So it’s no wonder that the discovery of a possible habitable planet around the sun’s nearest neighbour star, Proxima Centauri, a few years ago generated a lot of […]
Another “putting things into perspective” video which I liked, showing how big space is, and actually how far the nearest stars from us.
On March 24, 2017, astronomers led by Carnegie’s Meredith MacGregor and Alycia Weinberger discovered that a giant stellar flare erupted from Proxima Centauri, the closest star to the Sun (Proxima Centauri means ‘nearest [star] of Centaurus’), using data from the Atacama Large Millimeter/submillimeter Array (ALMA). The huge flare was 10 times larger than a major […]
Scientists spotted water in the atmosphere of 51 Pegasi b, one of the first exoplanets ever been discovered. It is around 50 light years away – so we can call it a “nearby” exoplanet – and it is in the constellation of Pegasus. 51 Pegasi b has not marked a breakthrough in astronomical research for […]
Proxima Centauri b, the Earth-like planet orbiting the red dwarf Proxima Centauri may have oceans, scientists say. The planet was discovered in August 2016 and caused excitement because it’s in the habitable zone of its star, and it’s rocky. And it’s in the Alpha Centauri, the closest star system to us! Researches of France’s National […]
On August 24, 2016, a group of scientists led by Dr. Guillem Anglada-Escude at the Queen Mary University of London, announced the discovery of a terrestrial exoplanet orbiting the red dwarf Proxima Centauri, the nearest known star to the Sun. Proxima Centauri is a Latin idiom, meaning “nearest (star) of Centaurus” (1). The new planet is […]
Is it possible for humanity to visit other stars (or other stars that have planets, actually) in the future? Earth is our one and only home. As Carl Sagan said (Pale Blue Dot: A Vision of the Human Future in Space), “On Earth, everyone you love, everyone you know, everyone you ever heard of, every […]
