WASP-18b - which is 10 times more massive than Jupiter - has a choking atmosphere consisting of deadly carbon monoxide.

Researchers from the agency have found the factor that could have helped in maintaining subsurface water under these worlds.

One of the most alarming images that was taken this year shows the Larcen C ice shelf breaking off and drifting to sea.

The ISS will install a new experimental sensor that can calculate the size, trajectory and impact of space debris that is less than a millimetre in size.

The rover will use new science instruments to hunt signs of ancient microbial life on the Martian surface.

Nasa Astronaut Randy Bresnik took time out of his busy schedule to film this incredible footage of Earth from space.

Nasa is working with a group of five high school and college students in a bid to improve virtual reality technologies.

Nasa has been building, studying, and developing aircraft and spacecraft for decades now and its contribution to aviation is immense.

The crew at the International Space Station plan to enjoy pouches of turkey, mashed potatoes, and cranberry-apple dessert to celebrate the national holiday.

The final shot was created from a series of images taken when Cassini spacecraft was approximately 1.1 million kilometres from Saturn.

The next Mars rover will have chainmail wheels that can carry more load which means more scientific equipment.

The AI-backed drone uses cameras to track its position and matches it with a pre-loaded map to move around and avoid obstacles.

The telescope will be launched into space by European Space Agency's Ariane 5 rocket sometime between March and June 2019.

Although the opposition called for calm, at least two people were killed in protests after the court upheld President Uhuru Kenyatta's re-election in a repeat vote that the opposition boycotted.

Jupiter is a planet that is known for its size and the Great Red Spot. Here are a few more of its features that are worth knowing about.

Conspiracy theorists have dragged up an image from 1972, claiming it proves that the moon landings took place in a studio

The JPSS-1 will orbit Earth 14 times a day from pole to pole, making detailed readings of weather, temperature and other long term patterns.

The Gradient Fingerprint Mapping system allows researchers to study the effects of melting ice sheets in Greenland and Antarctica on 293 major port cities.

Nasa has been looking at Earth with satellites for decades now and there is a lot of information that the space agency has in the form of images. Here are a few of the best ones.

The plane can be seen tethered to a Chinook, lifted to an altitude of 12,400 feet and landing only with its 'lifting body design'.

Nasa plans to continue studying the effects of space on humans, with several missions lined up over the coming years.

After delays caused by a stray aircraft just two minutes before the launch of Antares on 11 November, the rocket was relaunched the next day and is now on its way to the ISS.

The massive SLS rocket will carry four astronauts in Orion spacecraft and will produce a thrust of 8.8 million pounds at lift off.

In 2019, Nasa's New Horizons spacecraft will fly past a mysterious, distant object - currently known as (486958) 2014 MU69 - in the outer regions of the solar system.

Six researchers spent 8 months living in total isolation inside a small dome to assess the psychological impact of an extended Mars mission.

The spacecraft will be lifted using a Chinook and will then be dropped. The craft will have to find its way back to the runway, gliding without engine assistance.

The first configuration of the Space Launch System (SLS) vehicle, called Block 1, will use twin five-segment solid rocket boosters and four RS-25 liquid propellant engines.

The companies hope flying cars can be a reality by 2020. Dallas and Dubai will be the first cities to test the technology, followed by Los Angeles.
