Gaia, ESA’s revolutionary stellar cartographer, set to transform astronomy

Gaia, ESA’s revolutionary stellar cartographer, set to transform astronomy On September 14, the team will release its first galaxy map, comprising more than two million stars and other objects, and with it a full 19 papers by Gaia astronomers.To deliver this information, Gaia is using one of the oldest techniques in astronomy: parallax, or the extent to which an object seems to move as your position changes.

Closest exoplanet Proxima b remains mysterious, in the absence of direct observation

Closest exoplanet Proxima b remains mysterious, in the absence of direct observation The best we can do right now is make some educated guesses about conditions on Proxima b.According to researchers at France’s CNRS, there’s at least a possibility that Proxima b has liquid oceans on the surface.

This week in space: gravity waves, NASA’s Mars shot, and a new ‘super Jupiter’

This week in space: gravity waves, NASA’s Mars shot, and a new ‘super Jupiter’ That’s why LIGO wants your help, or at least your computer’s.President Obama told the nation he thinks it’s pretty important that we send humans to Mars “by the 2030s.

New Project Blue space telescope to image exoplanets in Alpha Centauri

New Project Blue space telescope to image exoplanets in Alpha Centauri Now a just-announced collaboration called Project Blue has been founded to launch a lightweight, low-overhead space telescope, to look at the two largest stars in that system, Alpha Centauri A and B.The idea is that the Project Blue telescope would directly image any orbiting planets within the stars’ habitable zones.

Trouble around Mars and Jupiter: this week in space

Trouble around Mars and Jupiter: this week in space NASA and ESA are joining forces to try to re-establish communications between Schiaparelli and its sister spacecraft, TGO, or even Mars Express or the Mars Reconnaissance Orbiter, all of which are active in orbit around Mars.A little further out, Eta Carinae is a colossal binary star system that’s really tearing up its environment.

Nearby exoplanet Proxima b could be a habitable ocean world

Nearby exoplanet Proxima b could be a habitable ocean world That’s not the case with Proxima b, a small exoplanet that orbits the nearest star to our own, Proxima Centauri.Scientists haven’t been able to spot Proxima b transiting its star yet, but a new study of the Proxima Centauri system shows how Proxima b could be a habitable ocean planet.

The majority of habitable zone planets around red dwarf stars may be 'water worlds'

The majority of habitable zone planets around red dwarf stars may be 'water worlds' Finding a plausibly habitable planet in the Goldilocks zone around Proxima Centauri B, along with one around the even smaller red dwarf Trappist-1, were wake-up calls.They showed everyone we’d been paying less attention to red dwarf stars than we probably should, because red dwarf stars could play host to many more habitable-class planets than we knew.

New telescope chip enables clearer view of alien worlds

New telescope chip enables clearer view of alien worlds The new development comes in the form of an optical chip that can be used to upgrade an existing telescope.Steve Madden said the chip worked much like active noise-canceling headphones.

NASA, SpaceX, and Virgin Galactic dominate the news: this week in space

NASA, SpaceX, and Virgin Galactic dominate the news: this week in space His legacy as a combat pilot, spaceman, senator, and loving family man will succeed him, along with the John Glenn Research Center in Cleveland.Godspeed, John Glenn.

The year in space: Supernovas, gravitational waves, theoretical planets, and Hammer pants

The year in space: Supernovas, gravitational waves, theoretical planets, and Hammer pants The Great Observatory is still going strong after its 2009 tuneup, and now the Space Telescope Science Institute has a little bit more scratch to keep the Hubble project running until 2021.This year, the International Space Station made its 100,000th orbit around our planet.

What is the Fermi Paradox?

What is the Fermi Paradox? The so-called Fermi Paradox comes up whenever we talk about the search for life outside our solar system, but what does the Fermi Paradox say about our place in the universe?It includes factors for the number of stars, the probability of habitable planet formation, the development of intelligent life, and so on.

Astronomers may have figured out why alien planets lack exomoons

Astronomers may have figured out why alien planets lack exomoons Astronomers have found a great many exoplanets out there among the stars, but one thing they have not found is exomoons.There’s no evidence of moons orbiting any of the planets we’ve found orbiting other stars, and it’s not clear why.

Scientists devise tiny spacecraft with giant light sails to visit nearest exoplanet

Scientists devise tiny spacecraft with giant light sails to visit nearest exoplanet Astronomers announced several months ago that there is most likely a small Earth-like planet in orbit of Proxima Centauri.Scientists are already working on theoretical ways we could send a tiny probe to investigate Proxima Centauri with the aid of a giant laser.

This week in space: Boeing, SpaceX, and tiny satellites

This week in space: Boeing, SpaceX, and tiny satellites Just this week Boeing showcased a new line of sleek spacesuits made to go with its Starliner spacecraft, designed to take astronauts to the ISS.The new suits will be for takeoff, ascent, and re-entry, and they’re in Boeing’s signature shade of blue.

The Keck Observatory just delivered these exoplanet beauty shots by redirecting starlight into the eye of an optical storm

The Keck Observatory just delivered these exoplanet beauty shots by redirecting starlight into the eye of an optical storm Instead of obstructing photons, the vortex coronagraph “redirects” them away from the camera “using a technique in which light waves are combined and canceled out.” Dmitri Mawet, who developed the vortex coronagraph, compares the process with what happens at the eye of a storm.

The hunt is on! Huge public dataset may contain hints of exoplanets

The hunt is on! Huge public dataset may contain hints of exoplanets A team of astronomers led by the Carnegie Institution for Science made public on Monday an immense catalog of observations on nearby stars.The dataset is intended to be easily accessible for citizen scientists to engage in the search for exoplanets.

Insane X-ray 'superflares' may have made Proxima b uninhabitable long ago

Insane X-ray 'superflares' may have made Proxima b uninhabitable long ago The hype train for Proxima b is impressive.Newly published research from the Goddard Space Center suggests that Proxima b might not be as habitable as we think.

Scientists want you to help them find planets in this database of stars

Scientists want you to help them find planets in this database of stars So now, researchers are hoping that members of the public will use their free time to comb through and find hints of planets circling those alien suns.By checking out these measurements, scientists can actually learn more about how a star wobbles in its orbit.

Scientists observe first planet-induced stellar pulsations

Scientists observe first planet-induced stellar pulsations But researchers now claim to have found the first example of stellar pulsations caused by an exoplanet.The star HAT-P-2 is emitting visible pulses that seem to be a result of a particularly large exoplanet in a highly eccentric orbit.

Ivy League astronomers take exoplanet hunting open-source

Ivy League astronomers take exoplanet hunting open-source To demonstrate the utility of the data set, they used it to find more than 100 exoplanets, all within 100 parsecs of us.There’s even one orbiting a near neighboring star to our own Solar System, GJ 411, which lies about 8.
