Topic: Constellation LyraWritten by DC Agle
This unusual object – for now designated A/2017 U1 – is less than a quarter-mile (400 meters) in diameter and is moving remarkably fast. Astronomers are urgently working to point telescopes around the world and in space at this notable object. Once these data are obtained and analyzed, astronomers may know more about the origin and possibly composition of the object. ![]() This photon shows the path of A/2017 U1, which is an asteroid — or perhaps a comet — as it passed through our inner solar system in September and October 2017. From analysis of its motion, scientists calculate that it probably originated from outside of our solar system. (NASA/JPL-Caltech) «Read the rest of this article» Sections: Technology | No Comments
NASA’s Kepler Space Telescope searches for another EarthWritten by Whitney Clavin
To take a brief tour of the more prominent contenders, it helps to zero in on the “habitable zone” around their stars. This is the band of congenial temperatures for planetary orbits — not too close and not too far. ![]() A newly discovered exoplanet, Kepler-452b, comes the closest of any found so far to matching our Earth-sun system. A newly discovered exoplanet, Kepler-452b: from left, Kepler-22b, Kepler-69c, the just announced Kepler-452b, Kepler-62f and Kepler-186f. Last in line is Earth itself.

NASA’s Kepler Space Telescope finds Planet near the size of Earth orbiting in the Habitable Zone of another StarWritten by Whitney Clavin
The Kepler-62 system has five planets: 62b, 62c, 62d, 62e and 62f. The Kepler-69 system has two planets: 69b and 69c. Kepler-62e, 62f and 69c are the super-Earth-sized planets. ![]() The artist’s concept depicts Kepler-62f, a super-Earth-size planet in the habitable zone of a star smaller and cooler than the sun, located about 1,200 light-years from Earth in the constellation Lyra.

NASA’s Kepler Space Telescope spots new Planetary System with Small PlanetsWritten by Dr. Tony Phillips
The planets are located in a system called Kepler-37, about 210 light-years from Earth in the constellation Lyra. The smallest planet, Kepler-37b, is slightly larger than our moon, measuring about one-third the size of Earth. It is smaller than Mercury, which made its detection a challenge. ![]() This line up compares artist’s concepts of the planets in the Kepler-37 system to the Moon and planets in our own solar system. «Read the rest of this article» Sections: Technology | No Comments
NASA’s Hubble Space Telescope sees Ancient Stars in the Constellation LyraNASA’s Goddard Space Flight Center
However, this was not known when Charles Messier first observed it in January 1779. He described Messier 56 as “a nebula without stars,” like most globular clusters that he discovered — his telescope was not powerful enough to individually resolve any of the stars visible here, making it look like a fuzzy ball through his telescope’s eyepiece. We clearly see from Hubble’s image how the development of technology over the years has helped our understanding of astronomical objects. ![]() Hubble Captures a Collection of Ancient Stars (Credit: NASA & ESA, Acknowledgement: Gilles Chapdelaine) «Read the rest of this article» Sections: Technology | No Comments
How to See the Best Meteor Showers of the Year: Tools, Tips and ‘Save the Dates’NASA’s Jet Propulsion Laboratory
First a word about the moon – it is not the meteor watcher’s friend. Light reflecting off a bright moon can be just as detrimental to good meteor viewing as those bright lights of the big city. There is nothing you can do except howl at the moon, so you’ll have to put up with it or wait until the next favorable shower. «Read the rest of this article» Sections: Technology | No Comments
