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.
VANDERBERG SPACE FORCE BASE, Calif. (ULA Mission Update) — Everything is progressing toward the ULA Atlas V launch carrying the Landsat 9 mission for NASA and the U.S. Geological Survey. The mission is planned to lift off on Mon., Sept. 27 at 11:11 a.m. PDT from Space Launch Complex-3 at Vandenberg Space Force Base in California.
Live broadcast coverage of launch will begin at 10:30 a.m. PDT on Sept. 27 and will broadcast live on NASA TV. Live launch updates and webcast available at: www.ulalaunch.com
PARIS (ESA PR) — ESA’s large-class science missions for the timeframe 2035-2050 will focus on moons of the giant Solar System planets, temperate exoplanets or the galactic ecosystem, and new physical probes of the early Universe.
“The selection of the Voyage 2050 themes is a pivotal moment for ESA’s science programme, and for the future generation of space scientists and engineers,” says Günther Hasinger, ESA Director of Science.
NASA FACT SHEET FY 2022 Budget Request Science ($ Millions)
NASA’s Science budget, managed by the Science Mission Directorate, includes five major science areas as well as the James Webb Space Telescope which is funded separately from Astrophysics. These areas include:
Earth Science to enhance understanding of Earth systems and to observe the effects of climate change. The Budget invests heavily in climate and applications research, begins formulation of the first four Designated Observable missions, and initiates the Earth System Explorers program (consistent with Decadal Survey recommendations). The Budget also supports the ongoing development of the Earth System Observatory including PACE, CLARREO Pathfinder, NISAR, SWOT, and Landsat 9.
