Space Dust Is Dark Matter

A small number of scientists defines space dust as the observable portion of dark matter. Space dust is comprised of small particles (about 0.1 mm) which reflect light on a very large scale. This is what can be seen of dark matter, not observable directly, but its hypothetical effects have been noticed.

SPACE: Chinese Space Walkers Stalk The Space Station

November 3, 2008: On September 27th, a Chinese Shenzhou space capsule came within 45 kilometers of the International Space Station, and two of the three crewmen made the first Chinese space walk (going outside the spacecraft in their space suits.) Later, a small, 88 pound microsatellite (the BX-1) was released from the Shenzhou. This was supposed to be a science experiment, but the fact that the Shenzhou came so close to the International Space Station, and then released a smaller, maneuverable (via small gas jets) BX-1, indicated another satellite destruction drill. The BX-1 could easily have been directed at the nearby space station, and destroyed it.

SPACEHAB Sees Opportunity in Space Florida's Launch Complex

SPACEHAB, Incorporated (NASDAQ:SPAB), and its Astrotech subsidiary, leading providers of commercial space services, join with Space Florida in recognizing the immense opportunities for America's commercial space program in the joint Air Force Space Command and Space Florida Dedication Ceremony of Launch Complex 36. The Ceremony marked the symbolic "groundbreaking" following the announcement by the Air Force Space Command of its commitment to commercial space and its intention to lease LC36 at Cape Canaveral Air Force Station to Space Florida. The U.S. Air Force's official "intent to lease" the site to Space Florida includes the build-out of the launch pad to support multiple-customers and multi-vehicle configurations for commercial, civil and military customers.

A Chance to See Dark Matter

Most of the matter in the universe is the mysterious dark matter, which astronomers can detect through gravitational effects but cannot actually see. The visible matter, or baryonic matter, that we're familiar with seems to make up only about 5% of the known universe compared to the 25% of dark matter!

It's Official, Australia Needs a Space Agency

Dante_J writes "In the final report published by the Australian Senate inquiry into 'The Current State of Australia's Space Science & Industry Sector' entitled 'Lost in Space? Setting a new direction for Australia's space science and industry sector,' it calls for the formation of a 'Space Industry Advisory Council' to oversee the creation of a fully-fledged Australian Space Agency. Of the top 20 GDP nations, Australia is the only one without a Space Agency, which impacts on many aspects of ordinary life, not to mention Research and Engineering endeavors. Every satellite operated by Australia is owned by another party and the costs of this alone are comparable to that of a Space Agency. The report is a tidy piece that drew upon submissions form Andy Thomas, and an impressive collection of Australian Academics and Space Science entities fr

Dark Matter Discovered Near Solar System?

gpronger writes "The ATIC (Advanced Thin Ionization Calorimeter) has potentially discovered the presence of dark matter close (only 3000 light-years) to our solar system. The system detected a large amount of high energy cosmic rays which match the theoretical signature of dark matter annihilating itself. The universe is believed to be composed of about 25% dark matter, but there has been little evidence of it. This discovery, if correct, would be the first." The paper was published in Nature, but it requires a subscription to see beyond the abstract.

Are We Close to Finding Dark Matter?

Scientists say he search for the mysterious substance which makes up most of the Universe could soon be at an end. A massive computer simulation was used to show the evolution of a galaxy like the Milky Way, and analysts were able to "see" gamma-rays given off by dark matter. Dark matter is believed to account for 85 per cent of the Universe's mass but has remained invisible to telescopes since scientists inferred its existence from its gravitational effects more than 75 years ago. If the computations are correct, the findings could help NASA's Fermi Telescope to search for the dark matter and open a new chapter in our understanding of the Universe.

The ISS Marks 10 Years In Space

Matt_dk writes to point out the upcoming tenth anniversary of the International Space Station in two days' time. "On 20 November 1998, a Russian Proton rocket lifted off from the Baikonur Cosmodrome for a historic mission: It was carrying the first module of the International Space Station ISS, named Zarya (Russian for 'dawn'). This cargo and control module, which weighs about 20 tonnes and is almost 13 meters long, provides electrical power, propulsion, flight path guidance and storage space. The launch of the module... heralded a new era in space exploration, as, for the first time ever, lasting cooperation in space was achieved between Russia, the US, Europe, Canada and Japan. Over the next ten years, many other modules were brought into orbit, and ISS developed into the largest human outpost in space.

Mysterious Dark Matter Might Actually Glow

The strange stuff makes up about 85 percent of the heft of the universe. It's invisible, but researchers know it's there because there is not enough regular matter -- stars and planets and gas and dust -- to hold galaxies and galaxy clusters together. Some other unseen material, dubbed dark matter, must be gluing things together.

Simulation points scientists to dark matter

This simulation shows the projected distribution of dark matter in the Milky Way. Myriad concentrations of dark matter are embedded within the galaxy's halo, and their dense centers emit energetic gamma rays from the annihilation of particles.

Stars that Eat Dark Matter Live Longer

A recent study indicates that there are stars in the proximity of the Milky Way's core that feed on dark matter, thus prolonging their lifespan with more than a billion years. Finding them would possibly help understanding what dark matter really is and how exactly it functions.

The Whereabouts of Dark Matter Revealed

According to a Reuters article, a recent vast-scale simulation of the creation and evolution of a Milky Way-type of galaxy has indicated some potential places in space where scientists should search for dark matter. Although the existence of the matter that forms a huge part of the universe has been known for a long time, and theoretically proved, all efforts to actually discover it turned out to be useless. However, in light of their research, experts may yet stand a chance.

In a statement released on his website on 29 July 2008, McClelland revealed that he witnessed an eight to nine foot tall extraterrestrial in association with a Space Shuttle mission he was monitoring from the Kennedy Space Center.

Where will new Fermi telescope find dark matter?

More than a billion particles were included in a simulation of dark matter in a Milky Way-like galaxy. The annihilation of dark matter in a cloud-like halo around the galaxy should produce a diffuse glow of gamma rays that could be detected by NASA's new Fermi telescope (Simulation: Virgo Consortium)

Simulations Predict Where We Can Find Dark Matter

p1234 writes with this excerpt from the Max Planck Institute for Astrophysics: "Simulations by the Virgo team show how the Milky Way's halo grew through a series of violent collisions and mergers from millions of much smaller clumps that emerged from the Big Bang. ... If Fermi does detect the predicted emission from the Milky Way's smooth inner halo, then it may, if we are lucky, also see gamma-rays from small (and otherwise invisible) clumps of dark matter which happen to lie particularly close to the Sun. ... The largest simulation took 3.5 million processor hours to complete. Volker Springel was responsible for shepherding the calculation through the machine and said: 'At times I thought it would never finish.' Max Planck Director, Professor Simon White, remarked that 'These calculations finally allow us to see what the dark matter dis
