Here's your chance to name an exoplanet and its host star

Aug 06, 2019 - 7:36 AM

'The names of the exoplanet and its host star should be related to one another and they should be culturally or historically relevant to the Philippines,' says PAGASA

Apr 06, 2019 - 8:30 AM

There have been no direct observations of living organisms or fossils on Mars so far. But there are other types of evidence.

Saturn's rings are younger than the planet itself

Jan 18, 2019 - 9:44 AM

The sixth planet from the Sun formed about 4.5 billion years ago, along with the rest of the planets in our solar system, and spent the bulk of its existence without the characteristic rings it is known for today

When you look up, how far back in time do you see?

Jan 01, 2019 - 9:00 AM

Without really trying, you can see years into the past. And with the aid of a telescope you can see millions or even billions of years into the past with your very own eyes.

Scientists discover strange planet with 3 stars

Jul 08, 2016 - 2:35 PM

The planet named HD 131399Ab is located about 340 light years from Earth and is believed to be about 16 million years old

epa05413486 An undated handout artist's impression made avaiable by the European Southern Observatory (ESO) on 07 July 2016 showing view of the triple-star system HD 131399 from close to the giant planet orbiting in the system. The planet is known as HD 131399Ab and appears at the lower-left of the picture. Located about 320 light-years from Earth in the constellation of Centaurus (The Centaur), HD 131399Ab is about 16 million years old, making it also one of the youngest exoplanets discovered to date, and one of very few directly imaged planets. With a temperature of around 580 degrees Celsius and an estimated mass of four Jupiter masses, it is also one of the coldest and least massive directly-imaged exoplanets. EPA/L.

Rosetta, Philae to reunite on comet for Sept 30 mission end

Jul 01, 2016 - 11:20 AM

The data from Rosetta and Philae will continue to be analyzed for months and years to come

epa04487728 A handout picture released by the European Space Agency (ESA) on 13 November 2014 shows the panoramic view created from the first two CIVA images, confirming that Rosetta's lander Philae is safely on the surface of Comet 67P/Churyumov-Gerasimenko. One of the lander's three feet can be seen in the foreground. The 100-kilogram probe touched down on Comet 67P/Churyumov-Gerasimenko, seven hours after separating from its mothership Rosetta half a billion kilometres from Earth. Philae's task is to collect images and samples from the dusty iceball, which will give clues about the origins of the solar system. EPA/ESA HANDOUT HANDOUT EDITORIAL USE ONLY

Europe's comet orbiter back after 'dramatic' silence

Jun 02, 2016 - 7:30 PM

UPDATED The Rosetta spacecraft returns to normal operations after the European Space Agency lost contact with it for nearly 24 hours over the weekend

epa04799978 (FILE) A file picture released on 02 March 2004 shows a computer generated image of space probe Rosetta (R) during the approach to the comet 67P/Churyumov-Gerasimenko. The European space probe Rosetta was successfully launched on a mission to the comet 67P/Churyumov-Gerasimenko from Kourou space centre in French-Guayana earlier today. Rosetta is expected to arrive at Churyumov-Gerasimenko in ten years time where it will release the landing robot Philae (L) on the surface of the comet. The comet lander Philae has awakened from seven months of hibernation and sent signals back to Earth, the European Space Agency said on 14 June 2015. Rosetta, a space probe, has studied the 67P/Churyumov-Gerasimenko comet for 312 days. It's Philae probe landed on the comet in November 2014 but shut down after some 60 hours as a result of insufficient charge in its batteries due to lack of sunlight at its location. Philae, a device approximately the size of a washing machine, was the first man-made device to make a controlled landing on a comet. EPA/ESA

Voyager discovers 'magnetic highway' at edge of solar system

Dec 04, 2012 - 2:22 PM

NASA s Voyager 1 spacecraft has encountered a magnetic highway at the edge of the solar system a surprising discovery 35 years after its launch the experts behind the pioneering craft said Monday December 3

"MAGNETIC HIGHWAY" This still image and set of animations show NASA's Voyager 1 spacecraft exploring a new region in our solar system called the "magnetic highway." In this region, the sun's magnetic field lines are connected to interstellar magnetic field lines, allowing particles from inside the heliosphere to zip away and particles from interstellar space to zoom in.
