Stellar Alignment Allows Opportunity To Find Planets Near Proxima Centauri
2013-06-04 08:55:53

John P. Millis, Ph.D. for redOrbit.com — Your Universe Online Besides our own Sun, the red dwarf star Proxima Centauri is the nearest star to Earth. As such, astronomers have sought to determine if planets orbit the tiny object. But because of its low brightness, and other issues, previous attempts to find planets using traditional methods have failed. But researchers have now determined that two unique opportunities -- one in October 2014, another in February 2016 -- will allow...

Closest Star System In A Century Found 6.5 Light Years Away
2013-03-11 16:28:34

Brett Smith for redOrbit.com - Your Universe Online Using data obtained from a NASA satellite, a Pennsylvania State University astronomer has identified the closest solar system to be found within the past 97 years. According to astronomer Kevin Luhman´s report in the Astrophysical Journal Letters, the newly identified system is a pair of brown dwarf stars and the third-closest system to the Sun. “The distance to this brown dwarf pair is 6.5 light years -- so close that...

Alpha Centauri B May Shed Light On Our Own Sun’s Anomalies
2013-02-20 12:52:10

Michael Harper for redOrbit.com — Your Universe Online As it turns out, studying our Sun can be rather difficult. It´s not the distance so much that keeps scientists guessing — although that certainly doesn´t help. The Sun´s intense heat also keeps scientists at bay, leaving them to make some of their observations and predictions based purely on context and far away measurements. One thing astronomers have been able to observe is a significant difference in...

How Do Wide Binary Stars Form
2012-12-05 13:48:14

Lee Rannals for redOrbit.com - Your Universe Online Scientists have reported in the journal Nature that they have figured out by using computer simulations how wide binary stars are able to form. Wide binary stars are two stars that orbit each other at a distance up to a light year. Some binary stars can be very close, while other pairs are extremely far apart. Astronomers have known about wide binary pairs for a long time, but how they form has remained a mystery. Now, astronomers...

Search For Alien Life Reignited
2012-10-20 08:52:06

April Flowers for redOrbit.com — Your Universe Online Listen to the podcast “How Planets Form” with redOrbit's Dr. John Millis and planet-hunting expert Dr. Eric Mamajek of the University of Rochester. In the past week, two new exoplanets have been confirmed; one by the Planet Hunters citizen science project that uses NASA's Kepler mission data, and the other by a European team. The existence of PH1 and the as-yet unnamed planet in Alpha Centauri will reignite the race...

Closest-Ever Exoplanet Discovered In The Alpha Centauri Star System
2012-10-17 14:08:24

Video 1 | Video 2 Lawrence LeBlond for redOrbit.com - Your Universe Online Astronomers have discovered a planet similar in mass to the Earth orbiting a star in the Alpha Centauri system – the nearest to Earth. Surpisingly, according to the astronomers, this planet which is just 4 light years away is also the lightest ever discovered around a star like our Sun. While the planet itself may be more similar in size and mass than Venus is to Earth, that´s where the good news...

Lyra Constellation -- Lyra (the lyre) is a prominent, although fairly small, northern constellation. It was one of Ptolemy's 48 constellations, and also counts among the modern 88 constellations. Its brightest star is Vega (Alpha Lyrae), which together with Altair (Alpha Aquilae) and Deneb (Alpha Cygni) forms the large asterism known as the Summer Triangle. Beta Lyr is a half separated (i.e. one of the stars reached its Rochevolume) eclipsing binary of a cream-white colour. The...

Centaurus Constellation -- Centaurus (the centaur) was one of the 48 constellations listed by Ptolemy, and counts also among the 88 modern constellations. A constellation of the southern hemisphere, mentioned by Eudoxus (4th century B.C.) and Aratus (3rd century B.C.), Ptolemy catalogued thirty-seven stars in it. It contains Proxima Centauri, the red dwarf that is the nearest known star (other than the Sun) to Earth, as well as Alpha Centauri, which is a double star to which Proxima...

Red Dwarf -- A red dwarf is a small star on the main sequence, either late K or M spectral type. They have a diameter and mass of less than one-third that of the Sun (down to 0.08 solar masses, which are Brown dwarves) and a surface temperature of less than 3,500 K. They emit little light, sometimes as little as 1/10,000th that of the sun. Due to the slow rate at which they burn hydrogen red dwarves have a enormous lifespan, estimates range from a tens of billions up to trillions of...

Vega -- Vega (Alpha Lyrae) is the lead star in the constellation Lyra, reaching near directly overhead the mid-northern latitudes, during the summer. It's a "nearby star" at only 25 light years distant and together with Arcturus and Sirius, one of the brightest stars in the Sun's neighbourhood. Vega is a vertex of the Summer Triangle. Its spectral class is A0V (Sirius, an A1V, is slightly less powerful) and it's firmly in the main sequence, fusing hydrogen to helium in its core....

Proxima Centauri -- The red dwarf star Proxima Centauri (also Alpha Centauri C), part of the Alpha Centauri star system, is the nearest star to our Earth other than the Sun. Proxima Centauri is roughly 4.22 light years from Earth, 270,000 times as far as the sun. Its apparent magnitude is 11 (very weak, as red dwarfs in general are: far too weak to be observable with the naked eye). Proxima Centauri has often been suggested as a logical first destination for interstellar travel....

  • In music, a work for a keyboard-instrument, like the pianoforte or organ, originally intended to utilize and display varieties of touch: but the term has been extended so as to include many irregular works, similar to the prelude, the fantasia, and the improvisation.
This word is Italian in origin, coming from the feminine past participle of 'toccare,' to touch.
