Exciting news! NASA’s planet-hunter TESS Space Telescope (Transiting Exoplanet Survey Satellite) has discovered its first Earth-sized exoplanet in its star’s habitable zone. The discovery was announced by NASA on January 7, 2020. The planet is named “TOI 700 d”. Using NASA’s Spitzer Space Telescope, astronomers confirmed the discovery and have modeled the planet’s potential environments […]
Earth’s atmosphere is leaking: around 90 tonnes of material escapes and streams out into space from our planet’s upper atmosphere every single day. To understand this escape, NASA launches rockets into space. The space agency also sends scientists to a tiny Arctic town named Ny-Ålesund (English: New Alesund) on the island of Spitsbergen in Svalbard, […]
Nick Longrich, University of Bath Are we alone in the universe? It comes down to whether intelligence is a probable outcome of natural selection or an improbable fluke. By definition, probable events occur frequently, improbable events occur rarely – or once. Our evolutionary history shows that many key adaptations – not just intelligence, but complex […]
Elizabeth Tasker (@girlandkat on Twitter), the UK astrophysicist working at the Japan Aerospace Exploration Agency (JAXA) and the author of the popular science book “The Planet Factory” Notes 1 says “the habitable zone is the worst name ever in the history of naming anything” in her perfect doodly she published on Twitter.
The American cartoonist Matthew Inman published a brilliant comic titled “The Oracle” on his website “The Oatmeal”. Inman’s comic gives the most probable answer (IMHO) to Fermi Paradox, which can be summarized in these three words – “Where is everybody”.
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!
Angelos Tsiaras, UCL With more than 4,000 exoplanets – planets orbiting stars other than our sun – discovered so far, it may seem like we are on the cusp of finding out whether we are alone in the universe. Sadly though, we don’t know much about these planets – in most cases just their mass […]
Thomas Moynihan, University of Oxford It is 1950 and a group of scientists are walking to lunch against the majestic backdrop of the Rocky Mountains. They are about to have a conversation that will become a scientific legend. The scientists are at the Los Alamos Ranch School, the site for the Manhattan Project, where each […]
Few topics in science command as much attention as the discovery of extrasolar planets – those as-yet-unseen worlds, light years beyond our own Sun. In the quest to learn whether we are alone in the cosmos, astronomers are teasing out subtle wobbles and periodic dimmings of distant stars: telltale signs that a planet, much too […]
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 […]
