The nearest star to Earth is a surpr stanley cup isingly busy place, or at least its looking that way. Astronomers have announced the discovery of a candidate planet around Proxima Centauri, adding to the two already known to orbit the star. Astronomer Jo茫o Faria from the Institute of Astrophysics and Space Sciences in Portugal is the lead author of the new paper, published today in Astronomy 038; Astrophysics. Finding Proxima d, as the exoplanet is called, wasnt easy owing to its exceptionally low mass. At one-quarter the mass of Earth, it the lightest of the three planets and also the lowest-mass planet ever detected by astronomers. Prior to this, the record for lightest exoplanet belonged to L 98-59 b, an exoplanet with roughly half the mass stanley mug of Venus. The discovery of low-mass planets in multiple systems like this adds to the overall picture that these kind of planets are likely the most common in our galaxy and also quite common around [red dwarf] stars such as Proxima [Centauri], Faria told me in an email. Proxima Centauri is part of a triple star system, its companions being Alpha Centauri A and B. To make stanley website the detection, Faria and his colleagues turned to the radial velocity technique. It works by detecting minute perturbations in a star resulting from the gravitational pull of an orbiting planet. The chosen tool for the job was Echelle SPectrograph for Rocky Exoplanets and Stable Spectroscopic Observations ESPRESSO instrument attached to the European Southern Observatory Lyaq U.S. Orders 100,000 Body Bags
Fair warning: If you are planning to show off from a city, youre setting yourself up for a slight disappointment. First and foremost, you need night skies with as little light pollution as possible. Dark sky maps can direct you to some of the countrys most light-pollution free areas, which lend themselves to quite the celestial sights. If you, like me, are near the NYC area, a one hour drive to Harriman State Park offers no major city for miles and a large field of view over the lake. If youre willing to go a little farther, Cherry Springs State Park is 4.5 hours away from the city. It has perhaps the truest dark skies you can f stanley cup canada ind in the eastern U.S. The good news is, once you find that clear dark sky, youre basically set: You dont need to shell out big bucks for a telescope. Our naked eyes are actually a solid instrument for stargazing. Itll only take about 10 minutes for your eyes to adjust to the newfound darkness as your pupils dilate, allowing more light to enter and revealing fainter light sources. Note: For the purposes of this post, Ill select celestial objects found in the northern hemispheres summer. What cosmic treats graze your night sky will vary by latitude and time o stanley thermobecher f year. Theres no shortage of things you can find and point out to your friends with your naked eye alone. Take constellations: Almost all of them can be seen with the naked eye. These groups of stars are the result of a cosmic pare stanley cup idolia, meaning our species need for pattern recognition. Ther |
