Segue 1 dwarf galaxy hints at universe’s first stars

The Segue 1, referred to as the "least chemically evolved galaxy known," could hint at the universe's very first stars, according to researchers who recently studied the tiny galaxy. Among all known galaxies, Segue 1 has significantly fewer stars and less heavy elements, revealing an estimated end to its evolution 13 billion years ago.

Saturn’s moon Enceladus may have ocean the size of Lake Superior under frozen surface

Saturn’s moon Enceladus may have ocean the size of Lake Superior under frozen surface

Scientists are looking at a number of celestial bodies in our solar system as potential habitats for life. One of the spots that we are looking at is one of Saturn's moons called Enceladus. This moon is particularly interesting because it is known to spew water into space. Gravity measurements suggest that the moon has an ocean between its rocky core and the icy shell that is about the size of Lake Superior.

X-37B classified spacecraft spends record 469 days in space

X-37B classified spacecraft spends record 469 days in space

In its third run, the X-37B, which is a highly secretive and classified spacecraft, has set a new record for the number of days in space. This unmanned craft has crossed 469 days of orbiting on a mission that is tightly sealed and is reporting to the Air Force and the U.S. Military. There is a possibility that it could be testing new space-based surveillance technologies.

NASA going deep space exploring with cosmic jets

NASA going deep space exploring with cosmic jets

NASA is planning to explore the depths of space with its most powerful launch vehicle, flying the cosmos more like a fighter jet than a traditional rocket. The US space agency aims to use the Space Launch System (SLS) to take probes, satellites, and even crewed stations like the proposed Deep Space Habitat far out through the galaxy, testing jet systems that would allow it to change course in real-time to avoid unforeseen obstacles.
