Little is known about this force and its its repulsive gravity, which is causing the expansion of the universe to accelerate. The riddles of dark matter and cosmic inflation, along with dark energy, these are the three pillars of modern cosmological theory," and none of them can be explained with physics that we know," Michael Turner, director of the Kavli Institute for Cosmological Physics says.
Last Breaths Of Dying Star Captured
Last breaths of dying sun-like star have been captured by scientists using NASA's Stratospheric Observatory for Infrared Astronomy (SOFIA). The object observed by SOFIA, planetary nebula Minkowski 2-9, or M2-9 for short, is seen in this three-color composite image. The SOFIA observations were made at the mid-infrared wavelengths of 20, 24, and 37 microns.
The Moon Is Not Earth's Only Natural Satellite
The Earth constantly captures small objects from (to) the NEO population and scientists construct a steady-state model of the Earth's temporary satellites. According to their studies, at any given time there is at least one one-meter-diameter object orbiting the Earth and the average satellite makes about 3 revolutions around the Earth in 9 months. Alien Species Living In The Inner Milky Way Could Be In Danger
Few people doubt there is intelligent alien life in the Milky Way galaxy, but where can we expect to find it? Astronomers think that while the inner sector of the MIlky Way Galaxy may be the most likely to support habitable worlds. Unfortunately some of these places are also most dangerous to all life-forms. Black Holes With No 'Table Manners' Eat Two Courses At Once!
It is still unknown how the supermassive black holes (SMBH) in galaxy centres accrete gas and grow. Researchers from the University of Leicester (UK) and Monash University in Australia have investigated how some black holes got so big so fast that they are billions of times heavier than the sun. Mercury Surprises Scientists
On March 17, MESSENGER (MErcury Surface, Space Environment, GEochemistry, and Ranging) completed its one-year primary mission, orbiting Mercury, capturing nearly 100,000 images, and recording data that reveals new information about the planet's core, topography, and the mysterious radar bright material in the permanently shadowed areas near the poles. Living Earth Simulator - Supercomputer Predicting The Future
In Douglas Adams book the Hitchhikers Guide to the Galaxy we encounter a machine called Deep Thought. It is the most powerful computer ever built. Deep Thought is capable of answering questions concerning life, the Universe, and simply everything. Now scientists are planning to create a similar machine. It is called the Living Earth Simulator (LES). Proof Of How The Universe Is Changing Though the universe is filled with billions upon billions of stars, the discovery of a single variable star in 1923 altered the course of modern astronomy. And, at least one famous astronomer of the time lamented that the discovery had shattered his world view. Bright Star In The Constellation Lyra Is Cooler Than The Human Body
The coldest class of stars have temperatures as cool as the human body. Astronomers hunted these dark orbs, termed Y dwarfs, for more than a decade without success. When viewed with a visible-light telescope, they are nearly impossible to see. Thermonuclear Burning In A Neutron Star Detected For The First Time!
It's a very important discovery! For the first time, an international team of scientists have detected all phases of thermonuclear burning in a neutron star, located close to the center of the galaxy in the globular cluster Terzan 5.
