Ground - based telescopes often follow up on Hubble's sightings, as does the Chandra X-ray Observatory, along with
other orbiting telescopes.

Planet Hunters, meanwhile, puts citizen scientists to work analyzing readings from NASA's Kepler space
telescope, designed to find Earth - like planets
orbiting other stars.
Once he'd found MU69, it was up to Buie and
others to calculate its
orbit and predict where its shadow would fall on Earth during the occultation last summer, resulting in those windswept
telescopes on Patagonia's beaches.
And this is just the latest in a series of stunning finds from Kepler, a space
telescope designed to search for Earth - size planets
orbiting other stars in what is called «the Goldilocks zone.»
This time they said we needed to show that even in
orbit, where it is dealing with cosmic rays and
other noise, the
telescope would be sensitive enough to detect Earth - size planets.
These
telescopes rely on detecting any Doppler shifting of the parent star caused by an
orbiting planet tugging it this way and that, but this method is vulnerable to interference from eruptions on the star's surface and
other distractions.
Astronomers using the TRAPPIST - South
telescope at ESO's La Silla Observatory, the Very Large
Telescope (VLT) at Paranal and the NASA Spitzer Space
Telescope, as well as
other telescopes around the world [1], have now confirmed the existence of at least seven small planets
orbiting the cool red dwarf star TRAPPIST - 1 [2].
Earlier this year the scientists of NASA's Kepler mission announced that their planet - hunting space
telescope had identified more than 1,200 possible exoplanets (worlds
orbiting stars
other than our own sun) in its first few months on the job.
William Borucki, of the NASA Ames Research Center in Mountain View, California, has captured the astronomy prize for two achievements: conceiving the observational technique of transit photometry that raised the tantalizing prospect of sighting Earth - like planets
orbiting other stars, and leading the 25 - year - long development of the Kepler mission, which in 2009 placed a
telescope in space to make those observations.
For a man obsessed with entities long - since expired, it seems cruelly fitting that Still, whom I sat with on that flight two years ago, may soon see the death of his own NASA program: managing the Kepler space
telescope, which
orbits the sun with a mission to find exoplanets near
other stars.
For this study the researchers used images taken from Earth between 2008 and 2014; they used, among
others, the astronomical cameras PlanetCam (developed by the Planetary Sciences Group itself) and Astralux, fitted to the
telescopes of the Calar Alto Observatory in Almería (Spain); in addition, they used the very high resolution images obtained by t he Cassini spacecraft, which has been
orbiting Saturn since 2004.
It is also the only
telescope and instrument in the world — in space or on Earth — that is capable of measuring reflected light from planets
orbiting around
other stars.
Using precise positional data from the National Science Foundation's Very Long Baseline Array (VLBA) and from optical
telescopes, Felix Mirabel, an astrophysicist at the Institute for Astronomy and Space Physics of Argentina and French Atomic Energy Commission, and Irapuan Rodrigues, also of the French Atomic Energy Commission, calculated that Scorpius X-1 is not
orbiting the Milky Way's center in step with most
other stars, but instead follows an eccentric path far above and below the Galaxy's plane.
A first step in answering that question is to determine if there are planets
orbiting other stars, a goal that remained unachievable for nearly 400 years after Galileo turned his
telescope to the heavens.
In
other spectral bands, especially at very short wavelengths, astronomers need
telescopes aboard satellites in
orbit around our planet, outside the obscuring layer of the atmosphere.
But in this age of space - based
telescopes, you may have wondered how a ground - based observatory like TMT (or some of the
other next - generation large terrestrial
telescopes) will get past the challenges of being on the ground instead of up in
orbit.
By tracking the motion of stars
orbiting close to Sgr A *, a team of German and Czech astronomers have analyzed 20 years of observations made by the VLT and
other telescopes using a new technique that pinpoints the positions of these stars.
From its
orbit approximately 1 million miles (1.6 million km) from Earth, the
telescope will uncover information about the birth of stars,
other solar systems and galaxies, and the evolution of our own solar system.
Though intended to find Earth - like worlds
orbiting other stars, the
telescope's data will be analyzed to determine if any of its targets cast unnaturally shaped shadows into Kepler's eye.
