ESA's Venus Express Probe Is On The Rise One Final Time
2014-07-14 14:35:17

John P. Millis, Ph.D. for redOrbit.com - Your Universe Online The planet Venus has often been referred to as Earth’s Twin, or Earth’s Sister, because in many ways it bears a striking similarity to the world we call home. But while it is roughly the same size, similar mass, possesses a magnetic field, and maintains an atmosphere, there are also some very important differences. Perhaps the most significant departure is the exact nature of Venus’s atmosphere. Surrounding our...

"Uchronia?-Atlantis Revealed" exposes the true location of Atlantis and touches on other controversial mysteries! NEW YORK, July 14, 2014 /PRNewswire/ -- In his greatly anticipated book, researcher and author Christos A. Djonis reveals a tangible discovery where, for the first time, all the physical characteristics of a proposed location match Plato's description of Atlantis. The geography is identical, the volcanic geology is there, and the flora and fauna chronologically match the...

redOrbit Staff & Wire Reports - Your Universe Online A long-lasting gamma-ray burst that was first observed last year contained traits similar to those expected from explosions of some of the earliest stars in the universe, claims a new study appearing in The Astrophysical Journal. According to the ESA, the long-lasting blast of extremely energetic radiation was identified as GRB130925A, and thanks to both ground- and space-based equipment, astronomers were able to track its origin...

April Flowers for redOrbit.com - Your Universe Online On July 14, NASA will launch a sounding rocket from White Sands Missile Range in New Mexico. A little before noon, the rocket will streak 180 miles into the atmosphere, sending it into the thermosphere layer, beyond the ozone's ability to block the sun's high energy light. Sounding rockets are small payload, scientific research rockets. Named for the nautical term "to sound," which means to take measurements, the rockets have been...

supermoon summer

April Flowers for redOrbit.com - Your Universe Online So-called supermoons are not a new phenomenon. However, the supermoon of July 2013 made headlines around the world, prompting a multitude of people to get out under the night sky to see it. The supermoon is approximately 14 percent larger and 30 percent brighter than a "regular" full moon. If the one supermoon of last summer caused such a stir, what will the three this summer cause? All three full moons this summer — July 12,...

Brett Smith for redOrbit.com - Your Universe Online When considering all the time, energy and money it takes to send astronauts into space, it quickly becomes apparent that heading into space isn’t the most efficient place to train an astronaut if it can be done right here on Earth. That’s the idea behind the European Space Agency’s CAVES program. Short for Cooperative Adventure for Valuing and Exercising human behavior and performance Skills – the program recently sent cavers...

John P. Millis, Ph.D. for redOrbit.com - Your Universe Online The holy grail of planetary astronomy is to find a solar system that mirrors our own. While a lot of effort has been placed on finding a planet with Earth-like properties – the right size, an atmosphere, the right temperature – are of equal importance in the search for a Sun-like star. Such a glowing orb would need to have a similar mass, temperature, and spectral type. These parameters are somewhat easy to measure, but...

Aricebo Observatory Picks Up Mysterious Radio Burst From Beyond The Milky Way
2014-07-11 13:19:30

John P. Millis, Ph.D. for redOrbit.com - Your Universe Online Over the last few years the Parkes radio telescope in Australia has detected a handful of short radio bursts emanating from deep space. This was an amazing discovery, except for the fact that no other radio facilities had seen such pulses, leading some to suggest that the instrument was detecting terrestrial signals. But now, the Arecibo radio telescope has made a similar detection that has the astronomical community talking....

John P. Millis, Ph.D. for redOrbit.com - Your Universe Online As astronomers have sought to understand the formation and evolution of galaxies, a handful of simple truths have emerged. Despite many questions remaining, we know that galaxies form in clusters, and create interlinked chains and structures that create a spider web across the cosmos. [ Watch the Video: Hubblecast 76: Merging Galaxies And Droplets Of Starbirth ] Because they often move through the Universe in such close...

Distant Earths May Need Balanced Friction Tides To Support Life
2014-07-10 12:52:42

Gerard LeBlond for redOrbit.com - Your Universe Online Friction generates heat and NASA scientists have developed a computer model that shows how friction may help distant Earth-sized planets survive dangerous orbits. Other star systems commonly house Earth-sized planets. To some, friction heat could be destructive, but given the correct amount of heat, it could be helpful in creating conditions to support life. “We found some unexpected good news for planets in vulnerable orbits....

Geometry
2014-01-02 10:21:51

Geometry is a branch of mathematics that is concerned with questions of shape, size, relative position of figures, and the properties of space. A mathematician who works in the geometry field is called a geometer. Geometry arose independently in numerous early cultures as a body of practical knowledge concerning areas, lengths, and volumes, with elements of a formal mathematical science emerging in the West as early as Thales. By the 3rd century BC, geometry was put into an axiomatic form by...

Stellar Astrophysics

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...

Ad Astra
2012-05-07 07:06:15

Ad Astra is a quarterly-published journal of the National Space Society (NSS). The name “ad astra” means “to the stars.” The journal was established following the merger of the L5 Society and the National Space Institute, which formed the NSS in 1987. The NSS is a non-profit aerospace advocacy and educational institution based in Washington DC. On November 28, 2007, the NSS announced MM Publishing Inc. as the newest publisher of Ad Astra. MM Publishing officially took on the role...

Columbia launched from Kennedy Space Center on October 22, 1992 at 1:09 PM EDT and landed at Kennedy on November 1 at 9:05 AM EST. The shuttle orbited 159 times at an altitude of 163 nautical miles at an inclination of 28.45 degrees and travelled 4.1 million miles. The mission lasted 9 days, 20 hours, 56 minutes, and 13 seconds. The mission launched several satellites for international partners. The primary mission objectives were the deployment of the Laser Geodynamic Satellite II...
