GREENBELT, Md. (NASA PR) — Scientists looking for signs of life beyond our solar system face major challenges, one of which is that there are hundreds of billions of stars in our galaxy alone to consider. To narrow the search, they must figure out: What kinds of stars are most likely to host habitable planets?
SYDNEY, Australia (University of Sydney PR) — Just months after its mission ended and a decade after its launch, glimmers of data detected by NASA’s Kepler space telescope in 2009 have been confirmed as evidence for a large, hot-Jupiter-like planet orbiting a star 2600 light years from Earth.
That 10-year mission to find distant planets around distant stars has shown that the universe is literally teeming with planets. There are more than 2300 confirmed exoplanets, ranging from huge gas giants to rocky worlds, perhaps not dissimilar to Earth.

NASA’s Transiting Exoplanet Survey Satellite (TESS) has found three confirmed exoplanets, or worlds beyond our solar system, in its first three months of observations.
The mission’s sensitive cameras also captured 100 short-lived changes — most of them likely stellar outbursts — in the same region of the sky. They include six supernova explosions whose brightening light was recorded by TESS even before the outbursts were discovered by ground-based telescopes.
EL SEGUNDO, Calif., Nov. 19, 2018 – In a new development in the search for potentially habitable planets far beyond our solar system, JPL and Aerospace are conducting a study to further develop an innovative deep-space concept that relies on a solar gravity lens (SGL) to enable enhanced viewing of exoplanets.
The SGL would provide 100-billion optical magnification, allowing it to show details as small as 10 kilometers across – similar to being able to spot something the size of New York City on an exoplanet.
BOULDER, Colo. (NASA PR) — On Thursday evening, NASA’s Kepler space telescope received its final set of commands to disconnect communications with Earth. The “goodnight” commands finalize the spacecraft’s transition into retirement, which began on Oct. 30 with NASA’s announcement that Kepler had run out of fuel and could no longer conduct science.
WASHINGTON (NASA PR) — After nine years in deep space collecting data that indicate our sky to be filled with billions of hidden planets – more planets even than stars – NASA’s Kepler space telescope has run out of fuel needed for further science operations. NASA has decided to retire the spacecraft within its current, safe orbit, away from Earth. Kepler leaves a legacy of more than 2,600 planet discoveries from outside our solar system, many of which could be promising places for life.
WASHINGTON (NASA PR) — Two vastly different NASA spacecraft are about to run out of fuel: The Kepler spacecraft, which spent nine years in deep space collecting data that detected thousands of planets orbiting stars outside our solar system, and the Dawn spacecraft, which spent 11 years orbiting and studying the main asteroid belt’s two largest objects, Vesta and Ceres.
BREMEN, Germany (ESA PR) — The construction of ESA’s Plato mission to find and study planets beyond our Solar System will be led by Germany’s OHB System AG as prime contractor, marking the start of the full industrial phase of the project.
WASHINGTON (National Academies PR) – To answer significant questions about planetary systems, such as whether our solar system is a rare phenomenon or if life exists on planets other than Earth, NASA should lead a large direct imaging mission – an advanced space telescope – capable of studying Earth-like exoplanets orbiting stars similar to the sun, says a new congressionally mandated report by the National Academies of Sciences, Engineering, and Medicine.
The study of exoplanets – planets outside our solar system that orbit a star – has seen remarkable discoveries in the past decade. The report identifies two overarching goals in this field of science:
To understand the formation and evolution of planetary systems as products of star formation and characterize the diversity of their architectures, composition, and environments.
To learn enough about exoplanets to identify potentially habitable environments and search for scientific evidence of life on worlds orbiting other stars.
GREENBELT, Md. (NASA PR) — In April 2018, NASA launched the Transiting Exoplanet Survey Satellite (TESS). Its main goal is to locate Earth-sized planets and larger “super-Earths” orbiting nearby stars for further study. One of the most powerful tools that will examine the atmospheres of some planets that TESS discovers will be NASA’s James Webb Space Telescope. Since observing small exoplanets with thin atmospheres like Earth will be challenging for Webb, astronomers will target easier, gas giant exoplanets first.
WASHINGTON, DC (AGU/AAS PR) ―The American Geophysical Union (AGU) and the American Astronomical Society (AAS) have received a grant from The Kavli Foundation to advance exoplanet science. This cooperative effort will help integrate the work of the AGU’s and AAS’s scientific communities through a joint steering committee, special sessions at both societies’ annual meetings, and topical conferences and workshops.
GREENBELT, Md. (NASA PR) — After a successful launch on April 18, 2018, NASA’s newest planet hunter, the Transiting Exoplanet Survey Satellite, is currently undergoing a series of commissioning tests before it begins searching for planets. The TESS team has reported that the spacecraft and cameras are in good health, and the spacecraft has successfully reached its final science orbit. The team continues to conduct tests in order to optimize spacecraft performance with a goal of beginning science at the end of July.
Every new mission goes through a commissioning period of testing and adjustments before beginning science operations. This serves to test how the spacecraft and its instruments are performing and determines whether any changes need to be made before the mission starts observations.
TESS is a NASA Astrophysics Explorer mission led and operated by MIT in Cambridge, Massachusetts, and managed by NASA’s Goddard Space Flight Center in Greenbelt, Maryland. Dr. George Ricker of MIT’s Kavli Institute for Astrophysics and Space Research serves as principal investigator for the mission. Additional partners include Northrop Grumman, based in Falls Church, Virginia; NASA’s Ames Research Center in California’s Silicon Valley; the Harvard-Smithsonian Center for Astrophysics in Cambridge, Massachusetts; MIT’s Lincoln Laboratory in Lexington, Massachusetts; and the Space Telescope Science Institute in Baltimore. More than a dozen universities, research institutes and observatories worldwide are participants in the mission.
MOFFETT FIELD, Calif. (NASA PR) — Earlier this week, NASA’s Kepler team received an indication that the spacecraft fuel tank is running very low. NASA has placed the spacecraft in a hibernation-like state in preparation to download the science data collected in its latest observation campaign. Once the data has been downloaded, the expectation is to start observations for the next campaign with any remaining fuel.
AI Accelerator to Focus on Key Challenges in Space Resources, Astrobiology, Space Weather, And Exoplanets to Benefit the Space Program and Humanity
MOUNTAIN VIEW, Calif. (SETI Institute/NASA PR) — The NASA Frontier Development Lab (FDL) has announced it will apply artificial intelligence (AI) to four key space challenges. FDL is an AI/machine learning research accelerator powered by a public/private partnership between NASA, the SETI Institute, commercial leaders in AI, and pioneers in the private space industry.
WASHINGTON, DC (NASA PR) — In the last decade we have discovered thousands of planets outside our solar system and have learned that rocky, temperate worlds are numerous in our galaxy. The next step will involve asking even bigger questions. Could some of these planets host life? And if so, will we be able to recognize life elsewhere if we see it?
