At the center of the image is the open star cluster NGC 6193, containing around thirty bright stars and forming the heart of the Ara OB1 association. The two brightest stars are very hot giant stars. Together, they provide the main source of illumination for the nearby emission nebula, the Rim Nebula, or NGC 6188, which is visible to the right of the cluster.
Is Saturn's moon Iapetus a jedi or a sith? NASA would claim it's both.
The clouds obscuring the surface of Venus can be easily penetrated by spacecraft radar, but now scientists from the National Radio Astronomy Observatory (NRAO) have used powerful ground-based radar technology located here on Earth to create surface maps of the planet.
GREENBELT, Md., March 10, 2015 /PRNewswire-USNewswire/ -- NASA has awarded the Mark IV and the Next Generation Very Long Baseline Interferometry Systems contract to the Massachusetts Institute
NASA’s planet-hunting Kepler spacecraft, which is responsible for discovering more than half of all known planets located beyond our solar system, celebrated its sixth birthday on Saturday, and we thought it would be a good time to take a look back its greatest achievements.
Once a star, the Veil Nebula is now a twisted mass of shockwaves that appears to be six-times the size of our moon, but it sure is nice to look at – as demonstrated by a high-resolution image captured by the Hubble Space Telescope and released by the ESA on Monday.
Stargazers in the northern hemisphere this month will have the opportunity to catch a glimpse of an unusual phenomenon known as the zodiacal light or the Pyramid of Light.
WASHINGTON, March 9, 2015 /PRNewswire-USNewswire/ -- NASA will host a teleconference at 11 a.m.
A new Rice University-led survey of one of the most active star-forming regions in the galactic neighborhood is helping astronomers better understand the processes that may have contributed to the formation of the sun 4.5 billion years ago. The survey of Carina Nebula is available online in the Astronomical Journal.
One explosion is cool. But four? That's great. Astronomers observed a star explode as a supernova 4 different times in this effect known as the Einstein Cross.
The prominent feature that allows for the existence of life on Earth is the Sun. Radiation from our closest star provides heat and energy to our planet, driving biological processes and providing the necessary conditions for liquid water to naturally exist. But our Sun is only but one star in this vast Universe. And as it turns out, most stars are quite different than the one that illuminates our day. For this reason, scientists have, for hundreds of years, attempted to study the other...
Image Caption: Artistic concept of a planetary system. Credit: Wikipedia/NASA/JPL-Caltech The term Astronomy encompasses a broad range of topics, including the study of stars, galaxies, and planets. In order to focus on the different areas of study, many subfields of astronomy emerge. One such area is the study of planets known, appropriately, as Planetary Astronomy. Observational Planetary Astronomy Even within the field of Planetary Astronomy, there are several divisions to...
Image Caption: The Hubble Extreme Deep Field (XDF) was completed in September 2012 and shows the farthest galaxies ever photographed by humans. Each speck of light in the photo is an individual galaxy, some of them as old as 13.2 billion years; the observable universe is estimated to contain more than 200 billion galaxies.

Image Caption: NGC 4414, a typical spiral galaxy in the constellation Coma Berenices, is about 56,000 light-years in diameter and approximately 60 million light-years distant. Credit: NASA/ESA/Wikipedia What is Astrophysics? For much of the modern age the term Astrophysics has been used synonymously with Astronomy. This interchange is so common that many textbooks even offer the two as having the same meaning. However, from a strictly historical perspective there are differences...
The Tropic of Capricorn, alternately called the Southern Tropic, is a marker of the most southerly latitude on the Earth at which the Sun can be directly overhead. This occurs at the December solstice, when the southern hemisphere is tilted towards the sun at its maximum degree. It is one of the five major circles of latitude that mark maps of the Earth. It presently lies 23 degrees 26’ 16’’ south of the Equator. Currently, the Tropic of Capricorn is drifting towards the north at...
