EXOPLANETS

There's a huge amount of variety among exoplanets – planets outside our solar system. There are water worlds, lava planets, egg-shaped worlds, planets with multiple suns, and even planets with no sun at all! What can we learn from all this weird, wondrous variety? What does it tell us about both the exoplanets themselves and our own home planet? Credit: NASA/JPL-Caltech

There's a helpful concept we use to help understand what distance from a given star you might expect to find planets with liquid water on their surface – liquid water being essential for life as we know it. It's called the habitable zone. Every star has a habitable zone, but where that zone lies is different for stars of different sizes and brightness. Credit: NASA/JPL-Caltech

Just as our own sun has many planets, other stars also have planets of their own. These are called exoplanets. The first of these was discovered in the 1990s, and since then, thousands of others have been found, thanks largely to the Kepler space telescope. What can we say about these other worlds? Are they similar to Earth? Might we ever go there? Let's get a closer look at some of these potentially habitable worlds now.

#EarthDay Imagine Earth was a planet in another solar system. A blue-hued, water-covered, cloudy exoplanet that’s light-years away and that our telescopes can best see when it passes in front of its Sun. Do you think we could tell if there is life there? Or that it’s even habitable? That’s what a research team, led by Johns Hopkins APL, wants to uncover through a conceptual Earth Transit Observer mission. The endeavor is not about confirming what everyone already knows (Earth is, in fact, habitable and inhabited); it’s about proving whether the method researchers currently use to determine if a planet is habitable — and that future telescopes such as NASA’s James Webb Space Telescope will use — actually works.

When we describe different types of exoplanets – planets outside our solar system – what do we mean by "hot Jupiters," "warm Neptunes," and "super-Earths"? Since we're still surveying and learning about the variety of worlds out there among the stars, it's sometimes helpful to refer to characteristics they share with planets we're familiar with in our own planetary system.

Exoplanets – planets outside our solar system – are everywhere. But why do we study them? What makes them so interesting? At NASA, we're surveying and studying exoplanets to learn all about their weirdness, their variety, and all the fascinating things they can tell us about how planets form and develop.

Scientists using NASA’s Hubble Space Telescope have found evidence that a planet orbiting a distant star that may have lost its atmosphere but gained a second one through volcanic activity. The planet, GJ 1132 b, is hypothesized to have begun as a gaseous world with a thick hydrogen blanket of atmosphere. Starting out at several times the diameter of Earth, this so-called “sub-Neptune” is believed to have quickly lost its primordial hydrogen and helium atmosphere due to the intense radiation of the hot, young star it orbits. In a short period of time, such a planet would be stripped down to a bare core about the size of Earth. That’s when things got interesting. For more information, visit https://nasa.gov/hubble.

Fede Rescigno joins us to talk about her work looking for Earth-like planets that orbit other stars. The National Space Academy has taken over the National Space Centre's social media for the week to showcase a range of people working in the space sector, and we'll be asking them YOUR questions about space careers. Fede is a PhD student at University of Exeter in the astrophysics department under Raphaëlle Haywood, whose research focuses on the detection and characterisation of small, potentially terrestrial planets around other stars than our Sun (which are known as exoplanets). Fede is a planet hunter and works on understanding stars better in order to find habitable Earth-like planets. She focuses on radial velocity variation, the tiny wobbles of stars due to orbiting bodies.

Astronomers estimate 400 billion planets orbiting stars in our galaxy, so the Milky Way is full of exoplanets. In the past two decades, researchers have discovered thousands, most of them with NASA’s Kepler Space Telescope and now its successor, the NASA Transiting Exoplanet Survey Satellite (TESS). Some of them are rocky, some are gaseous, and some are very, very odd. But there's one thing each of these strange new worlds has in common: All have advanced scientific understanding of our place in the cosmos. We invited two renowned astronomers who have dedicated their careers to studying exoplanets to share their lists of the top weird exoplanets. Andrew Vanderburg is an assistant professor of astronomy at the University of Wisconsin-Madison. His research has led to the recent discovery of a Jupiter-sized exoplanet around a White Dwarf star. Andrew will describe this incredible discovery and its consequences for the search for life beyond Earth. Jessie Christiansen, an astrophysicist with the NASA Exoplanet Science Institute at Caltech, works on NASA’s TESS to find the nearest planetary systems to Earth. Senior Astronomer Franck Marchis will moderate the conversation. It will be an opportunity to discuss the potential these space oddities have to teach us about the diversity of life we might find in our galaxy one day. #SETITalks #Exoplanets #NASATESS
