The Giant Magellan Telescope (GMT) is slated to be the first in a new class of extremely large telescopes, capable of producing images with 10 times the clarity of those captured by the Hubble Space Telescope. The GMT aims to discover Earth-like planets around nearby stars and the tiny distortions t...

Dr. Wendy Freedman, Chairman GMT, and Dr. Pat McCarthy, Director GMT, discuss the Giant Magellan Telescope's mirrors and the science that they will enable.

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

Since then, a total of 15 robotic missions led by various NASA centers have laid the groundwork for future human missions to the Red Planet. The journey to Mars continues with additional robotic missions planned...

American astrophysicist and cosmologist Neil deGrasse Tyson wrote and narrated a YouTube piece for Minute Physics called A Brief History of Everything, with the scientist explaining and condensing the epic 16 billion year history of the universe into a succinct eight minute video. While the basic co

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 New Horizons spacecraft has begun beaming back photographs of the surface of Pluto as it approaches the dwarf planet. . Report by Conor Mcnally.

New Horizons is the first mission to the Kuiper Belt, a gigantic zone of icy bodies and mysterious small objects orbiting beyond Neptune. This region also is known as the “third” zone of our solar system, beyond the inner rocky planets and outer gas giants. Johns Hopkins University Applied Physics L
