Perry Vlahos   At first thought to be a planet, Ceres was revealed to be a "new" body in a class called asteroids.

Happy birthday, Hubble! Here are some of the cosmic wonders it has revealed over 25 years

This is a mosaic image, one of the largest ever taken by NASA's Hubble Space Telescope of the Crab Nebula, a six-light-year-wide expanding remnant of a star's supernova explosion. Japanese and Chinese astronomers recorded this violent event nearly 1,000 years ago in 1054, as did, almost certainly, Native Americans.  The orange filaments are the tattered remains of the star and consist mostly of hydrogen. The rapidly spinning neutron star embedded in the center of the nebula is the dynamo powering the nebula's eerie interior bluish glow. The blue light comes from electrons whirling at nearly the speed of light around magnetic field lines from the neutron star. The  neutron star, like a lighthouse, ejects twin beams of radiation that appear to pulse 30 times a second due to the neutron star's rotation. A neutron star is the crushed ultra-dense core of the exploded star.  The Crab Nebula derived its name from its appearance in a drawing made by Irish astronomer Lord Rosse in 1844, using a 36-inch telescope. When viewed by Hubble, as well as by large ground-based telescopes such as the European Southern Observatory's Very Large Telescope, the Crab Nebula takes on a more detailed appearance that yields clues into the spectacular demise of a star, 6,500 light-years away. The newly composed image was assembled from 24 individual Wide Field and Planetary Camera 2 exposures taken in October 1999, January 2000, and December 2000. The colors in the image indicate the different elements that were expelled during the explosion. Blue in the filaments in the outer part of the nebula represents neutral oxygen, green is  singly-ionized sulfur, and red indicates doubly-ionized oxygen.

Happy birthday Hubble! To celebrate the 25th anniversary of the Hubble Space Telescope's lift-off from Earth on April 24, here are some of the cosmic wonders it has captured over its lifetime.

25 years of the Hubble space telescope

The Hubble Ultra Deep Field is an image of a small area of space in the constellation Fornax, created using Hubble space telescope data from 2003 and 2004. By collecting faint light over many hours of observation, it revealed thousands of galaxies, both nearby and very distant, making it the deepest image of the universe ever taken at that time.

Perry Vlahos   After a rocky start, in the past 25 years Hubble has given us unprecedented access to the universe’s secrets.

Alien hunting with Princess Ozma and friends

There is a connection between Mr Spock (played by the late Leonard Nimoy) and the first search for extraterrestrial intelligence (SETI).

Astronauts capture stunning photos of Pacific typhoon

Typhoon Maysak taken by astronaut Samantha Cristoforetti from the International Space Station.

Doyle Rice   Astronauts aboard the International Space Station captured some fantastic and awe-inspiring shots of Super Typhoon Maysak and its cavernous eye today.

Dark matter is even less like 'regular' matter than we thought

Rachel Feltman   Dark matter is even stranger than previously thought, a new study published in Science suggests.

Solar eclipse darkens Europe, thrills witnesses

The total eclipse of the sun would have been visible only in the Faroe Islands and the Norwegian archipelago of Svalbard in the Arctic Ocean. However, clouds obscured it in the Faroe Islands.

Dan Bilefsky and Melissa Eddy   Power firms in Germany, where about 6 per cent of energy is solar, had feared the sudden loss and return of sunlight would jolt the grid.


Lunar eclipse Easter weekend to be unusual and 'bloodless'

A lunar eclipse can only occur at full moon.

Perry Vlahos   On the night, the moon will pass through the edge of the Earth’s deepest shadow, so the eclipse will not be as dark is others, nor is the moon likely to turn red.

NASA discovers an underground ocean on Jupiter's largest moon

The year humans started to ruin the world

Geologists have determined the most powerful force on the planet.

Eric Roston   Astronomers have been telling us for nearly 500 years that humanity is not the most important thing in the universe. Evolutionary biologists established long ago that we're not even the greatest show on earth.
