Аннотированные Леониды An Annotated Leonid
29.11.1998

The 1998 Leonids Meteor Shower was perhaps the most photographed meteor event in history. Patient observers saw bright meteors streak across dark skies every few minutes, frequently leaving fading trails stretching across the sky. High above the Anza-Borrego Desert, a meteor was photographed streaking up from the radiant constellation of the Leonids: Leo.


Аресибо: Крупнейший телескоп Arecibo: The Largest Telescope
28.11.1998

The Arecibo radio telescope is currently the largest single-dish telescope in the world. First opening in 1963, this 305 meter (1000 foot) radio telescope resides in a natural valley of Puerto Rico. The Arecibo telescope has been used for many astronomical research projects, including


Одинокая нейтронная звезда A Lonely Neutron Star
27.11.1998

How massive can a star get without imploding into a black hole? These limits are being tested by the discovery of a lone neutron star in space. Observations by the Hubble Space Telescope have...


След метеора Twisting Meteor Train
26.11.1998

Blazing through the sky at 70 kilometers per second, 100 kilometers or so above planet Earth, many bright Leonid meteors left behind a persistent, smoke-like trail of glowing, hot, ionized gas. Twisting in high altitude winds, these trails or trains typically were visible for many minutes.

The bold, bright star patterns of Orion (right) are a familiar sight to even casual skygazers. But this gorgeous color photo also features a subtler spectacle - the faint stars of the Milky Way.


Болид Леонид над Канзасом A Leonid Bolide Over Kansas
24.11.1998

The 1998 Leonid Meteor Shower featured many bright events. Extremely bright meteors, known as bolides or fireballs, can briefly glow brighter than the full moon. Pictured above is a Leonid bolide caught during a five-minute, wide-angle exposure. The bolide was so bright it lit up the surrounding area, making otherwise dark trees visible.


Семь метеоров Леонид над обсерваторией Дж. Вайса Seven Leonids Over Wise Observatory
23.11.1998

More Leonids were visible at some places than others. In Israel, early in the morning of 17 November, it rained meteors though a clear sky. Observers there reported a peak rate for the 1998 Leonid Meteor Shower of about 600 meteors per hour.


Метеор Леонид взрывается A Leonid Meteor Explodes
22.11.1998

Click on the above image and watch a Leonid meteor explode. The tremendous heat generated by the collision of a small sand-bit moving at 70 kilometers/second with the Earth's upper atmosphere causes the rock-fragment to heat up, glow brightly, and disintegrate.


Крабовидная туманность The High Energy Crab Nebula
21.11.1998

This is the mess that is left when a star explodes. The Crab Nebula is so energetic that it glows in every kind of light known. Shown above are images of the Crab Nebula from visible light to the X-ray band.


Ловим падающую звездную пыль Catching Falling Stardust
20.11.1998

This carrot shaped track is actually little more than 5 hundredths of an inch long. It is the trail of a meteroid through the high-tech substance aerogel exposed to space by the shuttle launched EURECA (European Recoverable Carrier) spacecraft.
