SUN

The churning surface of a giant alien star is weird-looking in this photo, but the sun will look like that too one day.

Watch NASA announce the finalists for the next New Frontiers mission today. Who are the teams in contention and what do they want NASA to study next?

Cosmic ray activity was linked to the Medieval Warm Period around 1,000 AD and the Little Ice Age between 13th and 19th centuries.

Much like Earth, Jupiter also has an equatorial jet stream that reverses course at fixed periods. A NASA-led team has found the likely cause behind the reversal phenomenon.

The day of the year with the least amount of sunlight, winter solstice, is almost here.

Data obtained by NASA's Total Solar Irradiance Sensor showed sun is entering a 11-year cyclic electromagnetic output low and this could continue diminishing over time.

Australian researchers say they are very close to perfecting a laser-driven technique for creating fusion that dispenses energy and leaves no toxic radioactive waste.

The discovery was made using Google's machine learning algorithms, which exhibited a new way of analyzing data from the Kepler spacecraft.

Photos, shared on social media, showed Cade Huckabay's head, which had swelled up significantly after the sun exposure.

An international team of astronomers have measured the precise magnetic field properties close to a black hole in our own Milky Way galaxy and what they found might change everything we know about these mysterious phenomenon in space.

NASA has released a simulation of a planetary body that collided with Earth during the early days of it's formation which delivered precious metals such as gold and platinum.

An asteroid considered "potentially hazardous" by NASA is set to skim the Earth’s atmosphere just days before Christmas.

NASA's weather monitoring spacecraft has technological upgrades that should improve stability and provide three times better accuracy.

These striking fracture lines, captured in March, were caused by the Mars' crust stretching apart in response to ancient volcanic activity.

The studies may help determine the origins and science behind solar flares, which impact the entire solar system.

A team of researchers have debunked the Geo-engineering theory to cool down earth. Mimicking volcanic eruptions could leave a devastating effect on global weather patterns.

The programs were chosen from a pool of proposals accepted by Space Telescope Science Institute’s call for early release science proposals, and includes examining Jupiter and its moons.

A strange patch of extremely strong magnetic field occurred over Jordan in 1000 B.C. Could we be about to face another one?

Astronomers took a super close photo of a dying red giant star that tells them what our sun will look like when it’s elderly.

The first photos of the sun were taken in the first half of the 19th century and they paved the way for many important solar observations in the future.

NASA has extended the Dawn mission to 2018 to study Ceres up-close. The space probe hopes to capture the celestial event, which will help us understand the atmosphere around the dwarf planet.
