A flurry of solar activity in early March dumped enough heat in Earth's upper atmosphere to power every residence in New York City for two years. The heat has since dissipated, but there's more to come as the solar cycle intensifies.

The Parker solar probe spacecraft has been launched successfully by Nasa. It was sent off into space on board the Delta-IV Heavy Rocket from Cape Canaveral in Florida. The satellite is designed to fly within six million kilometres of the Sun – closer than ever before.

NASA’s New Horizons spacecraft is speeding towards Pluto for the first-ever flyby on July 14, 2015. Scientists are eager to collect data on the dwarf planet’s chemical and atmospheric makeup, and the Ralph spectrometer will do just that. Instrument scientist Dennis Reuter discusses Ralph, Pluto, and

NASA's Space shuttle last mission lift off. Shuttle Endeavour went to space for the last time on May 16th, 2011 at 8:56 AM EDT. By Wednesday May 18th they will have reached the space station and their return back after a 16 day mission is expected by early June, 2011

Mars is a cold and barren desert today, but scientists think that in the ancient past it was warm and wet. The loss of the early Martian atmosphere may have led to this dramatic change, and one of the prime suspects is the solar wind. Unlike Earth, Mars lacks a global magnetic field to deflect the s

Launched on Feb. 11, 2010, the Solar Dynamics Observatory, or SDO, is the most advanced spacecraft ever designed to study the sun. On June 5 2012, SDO collected images of the rarest predictable solar event--the transit of Venus across the face of the sun. This event happens in pairs eight years apa...

In the early hours of May 17, 2011 a beautiful filament erupted from the Sun and sent a cloud of plasma into space. This Coronal Mass Ejection was not aimed at Earth but most likely will interact with Earth's magnetic field two days later, creating some of these beautiful auroras. The second segment...

An idea born in unsettled times becomes a feat of engineering excellence. The most complex machine ever built to bring humans to and from space and eventuall...

NASA's Mars Exploration Rover Mission (MER) is an ongoing robotic space mission involving two rovers, Spirit and Opportunity, exploring the planet Mars. It began in 2003 with the sending of the two rovers—MER-A Spirit and MER-B Opportunity—to explore the Martian surface and geology.

The non-profit B612 Foundation aims to build, launch, and operate the first privately funded deep space mission—a space telescope in orbit around the Sun that will map the inner Solar System in search of asteroids that could impact Earth.
