Exocast-53 c – Exoplanet News

As always, the exocast team covers a few extraordinary recent exoplanetary results in Exocast-53 c: First off, Hannah briefly describes the problem with (and solution to) NASA Hubble’s elderly on-board computer Andrew details a few interesting results that emerged from the 2021 Goldschmidt conference, including updates on the bombardment of the early Earth, ancient methanogenic fossils, gasses trapped in diamonds, and new constraints on snowball earth. Hugh describes the ESA CHEOPS mission, and its serendipitous

Exocast-52b: Why is Venus important for exoplanets?

In this episode the Exocast team discuss Earth’s twin planet, Venus, and its link to exoplanetary science. We start with an overview of the past, present and future of Venusian exploration, from the first Soviet probes to the three newly-selected missions (DAVINCI+, VERITAS and EnVision) which will explore the atmosphere and surface of Venus more thoroughly than ever before. Then we turn to the open questions about Venus – its potential ancient habitability, the lack

Exocast-45d – Exoplanet News: new discoveries, characterisations, and formation research

On Exocast-45d we bring you the news from across exoplanet research this month with new discoveries, characterisations, habitability and formation papers. In America, WFIRST has been renamed the Nancy Grace Roman Space Telescope in honour to the pioneering “Mother Hubble”, while in Europe the LIFE mission kicked off. We have lots of new exoplanets being discovered (from TESS, NGTS, WASP and RVs), and un-discovered, as was the case for Fomalhaut b. Characterisation studies have also

Exocast-11b

In the eleventh episode, Exocast-11b: Hannah covers all the incredible news about the Trappist-1 system, talking us through the discovery of seven new earth-sized worlds around this nearby ultra-cool dwarf. Andrew talks about the philosophy of exoplanets, from the ancients, through the dark ages, and into the modern era. And Hugh sits in at the exocast newsdesk to cover the release of 60,000 HIRES RVs, new transit-hunting surveys MASCARA and BRing, the star HAT-P-2 beating to the rhythm of
