And there was a comprehensive story in  New Scientist magazine this past October on “The new age of sail,” as it was headlined. The subhead: “We are on the cusp of a new type of space travel that can take us to places no rocket could ever visit.” The article began by relating 17 th Century astronomer Johanne Kepler observing comets and seeing “that their tails always pointed away from the sun, no matter which direction they were traveling. To Kepler, it meant only one thing: the ...

 E-Mail In the search for planets capable of sustaining life, an international research team with members from ETH has taken a significant step forward. As the researchers reported recently in the journal Nature Communications, they found signs of a Neptune-sized planet in the Alpha Centauri star system, a mere 4.4 light years away from Earth. This exoplanet is located in a zone that may offer suitable conditions for life. The team was able to collect data with unprecedented sensitivity, thus...

“You're on Earth. There's no cure for that.” -Samuel Beckett In 2012, astronomers announced that the nearest star system to us, the Alpha Centauri system, possessed at least one exoplanet around it. A periodic signal that recurred just every 3.24 days was consistent with an Earth-sized exoplanet orbiting and gravitationally tugging on the second largest member of the star system: Alpha Centauri B.

As the researchers reported recently in the journal  Nature Communications, they found signs of a Neptune-sized planet in the Alpha Centauri star system, a mere 4.4 light years away from Earth. This exoplanet is located in a zone that may offer suitable conditions for life. The team was able to collect data with unprecedented sensitivity, thus registering even very weak signals. Earth is a disruptive factor   Thanks to the new process, the researchers have advanced one step closer to a major ...

By Karl GROSSMAN A report advocating rocket propulsion by nuclear power for U.S. missions to Mars, written by a committee packed with individuals deeply involved in nuclear power, was issued last week by the National Academies of Sciences, Engineering and Medicine. The 104-page report also lays out “synergies” in space nuclear activities between the National Aeronautics and Space Administration and the U.S. military, something not advanced explicitly since the founding of NASA as a civilian...

Possible planet found in habitable zone around Alpha Centauri Alpha Centauri A is the bright star to the left, which forms a triple star system with Proxima Centauri, circled in red. The bright star system to the right is Beta Centauri. Image: Wikimages Scientists using a new technique to image exoplanets in the mid-infrared may have just found a super-Earth-sized exoplanet around Alpha Centauri, the nearest star system to us. Whats more the planet is orbiting in its star’s habitable zone. At...

ksuadminFebruary 15, 2021 11 The dream of directly visualizing planets like Earth outside of the solar system got a little closer with a new technique developed by an international group of astronomers. As a demonstration, they have used it to study the Alpha Centauri system (which is closest to us, 4.3 light-years from here) and may already have found a planet there. The project, called NEAR (English acronym for New Lands in the Alfa Centauri region) involved installing updates for one of t...

EVAN GOUGH, UNIVERSE TODAY 13 FEBRUARY 2021 Astronomers using a new technique may have not only found a super-Earth at a neighbouring star, but they may also have directly imaged it. And it could be nice and cozy in the habitable zone around Alpha Centauri.   Its much easier to see giant planets than Earth-size planets. No matter which detection method is being used, larger planets are simply a larger needle in the cosmic haystack. But overall, astronomers are very interested in planets that...

Ravi Kopparapu, who works at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, and is the lead author of the study, explained this further, “On Earth, most of the nitrogen dioxide is emitted from human activity — combustion processes such as vehicle emissions and fossil-fueled power plants,” adding, “In the lower atmosphere (about 10 to 15 kilometers or around 6.2 to 9.3 miles), NO2 from human activities dominate compared to non-human sources. Therefore, observing NO2 on a ...
