Послание к ближайшим звездам A Cosmic Call to Nearby Stars
2.04.2006

If you could send a message to an alien civilization, what would you say? The people from the Cosmic Call project sent the above image as the first page of a longer message. The message was broadcast toward local stars by radio telescope during the summer of 1999. Another message was sent in 2003.


Телескоп Хаббла определяет срок годности лунного зеленого сыра Hubble Resolves Expiration Date For Green Cheese Moon
1.04.2006

Using the new camera on the Hubble Space Telescope, astronomers have been able to confirm that the Moon is made of green cheese. The telling clue was the resolution of a marked date after which the Moon may go bad.


Затмение Солнца и SOHO Solar Eclipse and SOHO
31.03.2006

Neither rain, nor snow, nor dark of night can keep the space-based SOlar Heliospheric Observatory (SOHO) from watching the Sun. In fact, from its vantage point 150 million kilometers sunward of planet Earth, SOHO's cameras can always monitor the Sun's outer atmosphere, or corona.


Когда бриллианты не вечны When Diamonds Aren t Forever
30.03.2006

The track of totality for the first solar eclipse of 2006 began early yesterday on the east coast of Brazil and ended half a world away at sunset in western Mongolia. In between...


Зеленое и черное северные сияния над Норвегией Green and Black Auroras Over Norway
29.03.2006

What causes gaps between aurora curtains? These unusual gaps can make Research using data from four Cluster spacecraft orbiting the Earth has likely found the secret: auroral gaps, sometimes knows as black auroras, are actually anti-auroras. In normal auroras, electrons and/or predominantly negatively charged particles fall toward Earth along surfaces of constant magnetic field.


Астероиды, пролетающие около Земли Animation of Asteroids Passing Near Earth
28.03.2006

How often does an asteroid whiz by the Earth? The above time-lapse animation follows the orbit of the Earth around the Sun for two months in 2002 as numerous asteroids, also known as minor planets, approach and pass by. Some asteroids appear out of nowhere as they are plotted only when they were discovered.


Неожиданно частые "лунотрясения" Moonquakes Surprisingly Common
27.03.2006

Why are there so many moonquakes? A recent reanalysis of seismometers left on the moon by the Apollo moon landings has revealed a surprising number of moonquakes occurring within 30 kilometers of the surface. In fact, 28 moonquakes were detected in data recorded between 1972 and 1977.


Обреченная звезда Эта Киля Doomed Star Eta Carinae
25.03.2006

Eta Carinae may be about to explode. But no one knows when - it may be next year, it may be one million years from now. Eta Carinae's mass - about 100 times greater than our Sun - makes it an excellent candidate for a full blown supernova.


Весна на севере Марса Northern Spring on Mars
24.03.2006

Astronomical spring came to planet Earth's northern hemisphere this week (and autumn to the south) with the equinox on March 20th. But on Mars, northern spring began on January 22nd. Still in northern...


Когда розы не красные When Roses Aren t Red
23.03.2006

Not all roses are red of course, but they can still be very pretty. Likewise, the beautiful Rosette Nebula and other star forming regions are often shown in astronomical images with a predominately red hue - in part because the dominant emission in the nebula is from hydrogen atoms.
