2015 has been an exceptionally exciting year in space, with NASA making back to back announcements about their new discoveries while providing a deeper insight into the worlds beyond our planet Earth.

2015 could also be called as the ‘Year of Pluto’ as NASA’s New Horizons spacecraft revealed the icy dwarf world and its moons in stunning details.

Of the many significant breakthroughs, here’s a list of the top five amazing space discoveries of 2015:

Dawn at Ceres

Earlier in February, NASA’s Dawn spacecraft captured the closest-ever images of Ceres - the best close-ups astronomers have ever captured of the dwarf planet.

Dawn spacecraft arrived at Ceres - celestial bodies believed to have accreted early in the history of the solar system - in March 2015. Dawn is the first spacecraft to visit a dwarf planet and the first to orbit two distinct targets in our solar system. During its nearly decade-long mission, Dawn will study the two most-massive protoplanets of the asteroid belt: Vesta and Ceres.

Exoplanet Kepler-452b

Earlier in 2015, NASA scientists discovered the exoplanet Kepler-452b, which was described as 'earth's cousin' because of its close similarities to our planet.

The breakthrough discovery was made by Kepler Space Telescope, which has found more than half of all known exoplanets to date.

Water on Mars

In September 2015, scientists have for the first time confirmed liquid water flowing on the surface of the present-day Mars, raising speculation about the possibility of some form of life being discovered on the Red Planet.

New changes in Jupiter’s Great Red Spot

Recently, new imagery from NASA/ESA Hubble Space Telescope revealed details never before seen on Jupiter - an elusive wave and changes to the planet’s Great Red Spot. The new images revealed a rare wave just north of the planet’s equator and a unique filamentary feature in the core of the Great Red Spot not seen previously.
