On 30 June 1908 at 7 o’clock in the morning a huge object fell through the sky. The object was so bright that the sun seemed dull in comparison. It fell to the earth and exploded with the power of a thousand Hiroshima bombs. The bomb fell near the Podkamennaya Tunguska River in Siberia.The shock wave completely destroyed the forest and huts 5-7 kilometres away. It felled trees that stood 25-30 kilometres from the explosion. A conductor stopped a train some 800 kilometres away thinking that one of the carriages had exploded. The bright fireball was even visible in Western Europe. The shock waves were spotted by almost every geographical observatory in use in 1908.The powerful explosion and the emission of redhot gases from the burning forest caused devastation to the region.

A few minutes after the explosion, a magnetic storm started which was registered in Irkutsk . It lasted more than four hours and was similar to the geomagnetic disturbances caused by a nuclear explosion. The area where these phenomena were observed is bound by the Yenisey River in the East, by the latitude of Tashkent-Stavropol-Sevastopol-Bordeaux in the South, and by the Atlantic coast in the West. The event has been written in history as “The White Nights of the summer of 1908.” On the night of 30 June it hardly became dark at all. This light was connected with the dawns which resemble the “volcanic twilight” which was observed after the eruption of Mount Krakatoa in 1883.At that time changes of the polarization of the twilight sky were observed. This phenomenon was noticed for2-3 days before the explosion in Tunguska. The changes were observed in ten different places at night on 29th and 30th June. The biggest anomalies occurred on the night after the explosion and were recorded in 150 places in Europe and Asia . The intensity of the explosion in the regions furthest from the explosion quickly died down and the cosmic fireball had for the most part finished by 4 July. However, in several parts of Europe the echo could be heard until 20 July. Within 19 years people had forgotten about the incident with the reasons for it were still unclear. When scientists came to explore the site, all they found was 2500 square metres of destroyed forest. Witnesses in neighbouring villages were found, who remembered the fireball flying through the night sky, the terrible noise and great clamour of the explosion. Explorers searched the area for evidence of amete......

Scientists find most Earth-like planet yet

WASHINGTON (Reuters) - European astronomers have spotted what they say is the most Earth-like planet yet outside our solar system, with balmy temperatures that could support water and, potentially, life. They have not directly seen the planet, orbiting a red dwarf star called Gliese 581. But measurements of the star suggest that a planet not much larger than the Earth is pulling on it, the researchers say in a letter to the editor of the journal Astronomy and Astrophysics. "This one is ...

Hubble spots "space jellyfish"

New photographs from the Hubble Space Telescope have revealed extraordinary images of planetary systems being formed. One such image shows a "cosmic jellyfish", a protoplanetary disc hit by particles from a nearby star."An oddarray of 30 newly released images from the Hubble Space Telescope reveal planetarysystems in the making. . The blobs and smudges, as astronomers described them, sit in the widely photographed Orion Nebula....

Dazzling new images reveal the 'impossible' on the Sun

The restless bubbling and frothing of the Sun's chaotic surface is astonishing astronomers who have been treated to detailed new images from a Japanese space telescope called Hinode. The observatory will have as dramatic an impact on our understanding of the Sun as the Hubble Space Telescope has had on our view of the universe beyond, scientists told a NASA press conference in Washington, DC, US, on Wednesday."Everything we thought we knew about X-ray images of the Sun is now out of dat...

"Waterworld" discovered 40 light years away

The most likely extrasolar planet to support life yet found has been discovered 40 light years away. The planet is thought to be mostly composed of water, is 6 times the size of the Earth and is in orbit around a red dwarf star."Astronomers havediscovered a new "waterworld" 40 light years away,raising the chances of the existence of Earth-like planets. . Evidence suggests it has an atmosphere, and astronomers believe it to be m...

Oddball Planet Puzzles Astronomers

A team of amateur and professional astronomers has discovered a mammoth orb more than 13 times the mass of Jupiter that whips around its parent star in fewer than four days and is considered an "oddball" planet among its exoplanet relatives. The new exoplanet, dubbed XO-3b, was described here at a meeting of the American Astronomical Society. The discovery came out of the XO Project, a collaboration between amateur and professional astronomers. "Of the 200-plus exoplanets found so far, ...

Water detected on distant planet

Water has been detected for the first time in the atmosphere of a planet outside our Solar System. The planet, known as HD 209458b, is a Jupiter-like gas giant located 150 light-years from Earth in the constellation Pegasus. Other scientists reported in February they were unable to find evidence of water in this planet's atmosphere, as well as in another Jupiter-like planet. Details of the research are published in the Astrophysical Journal. Understanding the distribution of waterin ...

'Cave entrances' spotted on Mars

Scientists studying pictures from Nasa's Odyssey spacecraft have spotted what they think may be seven caves on the surface of Mars. The candidate caves are on the flanks of the Arsia Mons volcano and are of sufficient depth their floors mostly cannot be seen through the opening. Details were presented here at the Lunar and Planetary Science Conference in Houston, Texas. Temperature data from Mars Odyssey's Themis instrument support the idea. The authors say that thepossible disco...

Probe reveals seas on Saturn moon

Nasa's Cassini probe has found evidence for seas, probably filled with liquid hydrocarbons, at the high northern latitudes of Saturn's moon Titan. The dark features, detected by Cassini's radar, are much bigger than any lakes already detected on Titan. The largest is some 100,000 sq km (39,000 sq miles) - greater in extent than North America's Lake Superior. It covers a greater fraction of Titan than the proportion of Earth covered by the Black Sea. The Black Sea is the E...

Astronomers claim galaxy record

Astronomers say they may have detected the light from some of the earliest stars to form in the Universe. They have pictures of what appear to be very faint galaxies that shone more than 13 billion years ago, a mere 500 million years after the Big Bang. The remarkable claim dramatically exceeds the current, broadly accepted record for the most distant detection. The Caltech-led team behind the work recognises there will be sceptics but says it believes its data is strong. It has publishe...

M-81 black hole bigger than thought

Astronomers have determined that the supermassive black hole at the center of the M87 galaxy is at least twice as large as previously thought, weighing 6.4 billion times the mass of our Sun it is the largest black hole ever measured."Using a new computermodel, astronomers have determined that the black hole in the center of the M87 galaxy is at least twice as big as previously thought.Weighing in at 6.4 billion times the S...
