Gravitational Lensing and Einstein Cross

How ‘Gravitational Lensing’ Made One Supernova into Four—‘Einstein Cross’

Medicine & Technology Nicknamed the “Einstein Cross” after the famous physicist who predicted the possibility of the phenomenon as a result of his theory of relativity more than a century ago, the formation was made possible by a strange occurrence known as gravitational lensing. When a galaxy or cluster is large enough, they can often bend light that passes through it. And when they are rather perfectly aligned with Earth, even small events too far to be seen can be magnified so that researchers are able to detect them.

What's Next for Dawn at the Dwarf Planet Ceres

NASA's Dawn spacecraft has completed its eight-year journey to the dwarf planet Ceres, but what lies ahead for the history making spacecraft while it orbits the planet that was never meant to be?
Mars with Water

Mars Once Had More Water Than the Arctic Ocean

Scientists believe that the Red planet once had more water on its surface than is found today in Earth's Arctic Ocean. However, over time Mars has lost 87% of this water to space.

Dawn Spacecraft Arrives to Ceres—Hear What NASA Has to Say About the Mission

After more than seven years of drifting in space, NASA’s Dawn spacecraft has finally achieved its primary mission of entering orbit around the dwarf planet Ceres. Becoming the first ever mission to achieve orbit around a dwarf planet, mission controllers with NASA’s Jet Propulsion Laboratory received confirmation this morning that the small orbiter had finally reached its destination.

Military Satellite Explodes in Space

An aging United States military weather satellite dubbed Defense Meteorological Satellite Program Flight 13 (DMSP-F13) exploded in orbit on February 3. The explosion occurred after the 20-year-old satellite experienced a sudden spike in temperature, producing at least 43 pieces of debris.

NASA Seeks to Improve GPS Communications with Study of Ionosphere

When you don't know how to get to where you are going, chances are you pull out a smartphone or other type of device with a Global Positioning System (GPS) to help guide you where you need to go. What you may not know is that the signals traveling between the GPS satellites and your devices can get distorted thanks to the Earth's upper atmosphere.

NASA Receives Proposals for More Solar System Exploration

NASA has received dozens of new proposals for robotic missions for launch in 2021 to explore different parts of the solar system. Scientists have submitted concepts for sending probes to the moon, asteroids, comets and other planets for a chance to win $450 million in federal funding for their mission.
Mars Rover Curiosity Dig Feb. 24

Curiosity Mars Rover Seeks Answers in the Rocks of Pahrump Hills

Finding some interesting chemistry in the rocks of Mars, NASA’s Curiosity Mars rover decided to investigate on Telegraph Peak earlier this week, boring into the Martian surface in search of answers. Though the rock powder poses new questions to the chemical composition of the planet, the car-sized Curiosity rover is far from reaching its final destination.

Methane Based Life Could Exist on Saturn’s Moon, Titan

In a new study published this week by researchers from Cornell University, the team of researchers has modeled a new methane-based life form that can metabolize and reproduce, similar to the oxygen-based life forms here on Earth. And more than that, the researchers say that these life forms could flourish in the harsh, cold environment of Saturn's moon, Titan. Titan's surface is filled with seas of liquid methane that researchers believe could harbor these methane-based cells.
