Леониды на фоне звезд A Leonids Star Field

As meteor after meteor streaked across a moonless sky, photographers across the world snapped pictures of the 2001 Leonids Meteor Shower. Many recognized this as the best meteor shower they had ever seen. In fact, the 2001 Leonids was the most active meteor shower since the mid-1960s.

The 2001 Leonids Meteor Shower gave quite a show to many parts of the world yesterday during the early morning hours. Many sleepy observers venturing into their own backyards were treated to several bright meteors per minute streaking across the sky.

Last night and tonight, a lucky few may see a meteor explode. As our Earth passes unusually close to debris expelled from Comet Tempel-Tuttle, many sand-sized particles from this comet are entering and burning up in the Earth's atmosphere.

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.

Will the Leonids storm this year? The annual Leonid meteor shower should peak this weekend and some predictions suggest that "storm" rates of a thousand or more meteors per hour are possible for observers located in eastern North and Central America during the early morning hours of Sunday, November 18.

Б/у "Колумбия" Recycling Columbia

Twenty years ago this week, the Space Shuttle Columbia became the first reusable spaceship. Its second trip to low Earth orbit and back again began on November 12, 1981, following its maiden voyage by only seven months.

Auroras in the north and south can be nearly mirror images of each other. Such mirroring had been suspected for centuries but dramatically confirmed only last month by detailed images from NASA's orbiting Polar spacecraft.

Is gravity the same over the surface of the Earth? No -- it turns out that in some places you will feel slightly heavier than others. The above relief map shows in exaggerated highs and lows where the gravitational field of Earth is relatively strong and weak.

Является ли загадочный объект послесвечением гамма-всплеска? Is Mystery Object an Orphan Afterglow

What is that unusual object? Astronomers can identify most objects that are imaged on the sky, but not all. Pictured above is one that currently defies classification. Attributes of the object include that it has unusual colors, appears to be fading as months go by, and appears to be associated with a distant galaxy.

Зарегистрированный Леонид An Annotated Leonid

The 1998 Leonids Meteor Shower was one of 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.
