GREENBELT, Md. (NASA PR) — Searching the universe for Earth-like planets is like looking for a needle in a haystack. To further this exploration, NASA is supporting the early-stage study of a concept for a hybrid observatory that would combine a ground-based telescope with a space-based starshade. These devices block glare from stars when observing planets outside our solar system, known as exoplanets, from the ground. The Hybrid Observatory for Earth-like Exoplanets (HOEE) would convert the largest ground telescopes into the most powerful planet finders ever made – and the public has an opportunity to be part of this groundbreaking endeavor.
SWINDON, UK (UK Space Agency PR) — The UK Government will invest £30 million to secure the UK’s leading role in developing a space telescope to explore exoplanets.
Due to launch in 2029, Ariel’s mission is to understand the links between a planet’s chemistry, its evolution and its host star, by characterising the atmospheres of 1,000 known planets outside our solar system.
The count of confirmed exoplanets just ticked past the 5,000 mark, representing a 30-year journey of discovery led by NASA space telescopes.
PASADENA, Calif. (NASA PR) — Not so long ago, we lived in a universe with only a small number of known planets, all of them orbiting our Sun. But a new raft of discoveries marks a scientific high point: More than 5,000 planets are now confirmed to exist beyond our solar system.
NASA is funding research by John Mather of Goddard Space Flight Center into the development of a massive orbiting star shade that would allow ground-based telescopes to search for Earth-like exoplanets.
PARIS (ESA PR) — Plato, ESA’s next-generation planet hunting mission, has been given the green light to continue with its development after the critical milestone review concluded successfully on 11 January 2022.
The infrared observatory may help answer questions about planets outside our solar system, or exoplanets, including how they form and what drives weather in their atmospheres.
PASADENA, Calif. (NASA PR) — Two new studies using data from NASA’s retired Spitzer Space Telescope shed light on giant exoplanets and brown dwarfs, objects that aren’t quite stars but aren’t quite planets either. Both studies will be the focus of virtual news conferences hosted by the American Astronomical Society on Jan. 13.
PARIS (ESA PR) — ESA’s exoplanet mission Cheops has revealed that an exoplanet orbiting its host star within a day has a deformed shape more like that of a rugby ball than a sphere. This is the first time that the deformation of an exoplanet has been detected, offering new insights into the internal structure of these star-hugging planets.
The planet, known as WASP-103b is located in the constellation of Hercules. It has been deformed by the strong tidal forces between the planet and its host star WASP-103, which is about 200 degrees hotter and 1.7 times larger than the Sun.
WASHINGTON (NASA PR) — In 2021, NASA completed its busiest year of development yet in low-Earth orbit, made history on Mars, continued to make progress on its Artemis plans for the Moon, tested new technologies for a supersonic aircraft, finalized launch preparations for the next-generation space telescope, and much more – all while safely operating during a pandemic and welcoming new leadership under the Biden-Harris Administration.
MOFFETT FIELD, Calif. (NASA PR) — Scientists recently added a whopping 301 newly validated exoplanets to the total exoplanet tally. The throng of planets is the latest to join the 4,569 already validated planets orbiting a multitude of distant stars. How did scientists discover such a huge number of planets, seemingly all at once? The answer lies with a new deep neural network called ExoMiner.
PARIS (ESA PR) — ESA and Airbus have signed a contract to move forward with the design and construction of the Atmospheric Remote-sensing Infrared Exoplanet Large-survey, Ariel, planned for launch in 2029.
Ariel is the third in a trio of dedicated exoplanet missions conceived by ESA focusing on various aspects of this rapidly evolving subject area. It will follow Cheops, which launched in 2019, and Plato, scheduled for launch in 2026.
How do we understand the significance of new scientific results related to the search for life? When would we be able to say, “yes, extraterrestrial life has been found?”
NASA scientists are encouraging the scientific community to establish a new framework that provides context for findings related to the search for life. Writing in the journal Nature, they propose creating a scale for evaluating and combining different lines of evidence that would ultimately lead to answering the ultimate question: Are we alone in the universe?
PASADENA, Calif. (NASA PR) — A new study shows how the chemicals in an exoplanet’s atmosphere can, in some cases, reveal whether or not the temperature on its surface is too hot for liquid water.
In our solar system, planets are either small and rocky (like Earth) or large and gaseous (like Neptune). But around other stars, astronomers have found planets that fall in between – worlds slightly larger than Earth but smaller than Neptune. These planets may have rocky surfaces or liquid-water oceans, but most are likely to be topped with atmospheres that are many times thicker than Earth’s and opaque.
STRASBOURG, France (Europlanet Society PR) — An international team of astronomers has not only detected clouds on the distant exoplanet WASP-127b, but also measured their altitude with unprecedented precision. A presentation by Dr Romain Allart at the Europlanet Science Congress (EPSC) 2021 shows how, by combining data from a space- and a ground-based telescope, the team has been able to reveal the upper structure of the planet’s atmosphere. This paves the way for similar studies of many other faraway worlds.
