Earth's natural satellite is comparatively large. It's thefifth biggest moonin theentire solar system, where more than 190 different moons have been discovered overall. Here's something else that makes Earth's moon stand out: Every other planet that orbits the sun either has no moons at all...
The simulations also matched two other important properties of the Earth-moon system: the moon’s relatively high speed as itorbits the planet, and the fact that the moon has more iron oxide than Earth – iron oxide would have been more abundant in liquid rock than solid. If t...
NASA has divided the challenge of getting to Mars into three stages; Earth reliant, proving ground and Earth independent. In the coming decades the space agency will continue to gather information from experiments aboard the International Space Station, so that crews can live in deep space without...
NASA lost contact with STEREO-B in 2014, which remained out of contact except for a brief period in 2016. STEREO-A remains fully functional. The Solar and Heliospheric Observatory (SOHO), which last year celebrated 25 years in space, has been one of the most important solar missions to ...

Between the year 1969 and 1972, under the legendary Apollo program, NASA performed six successful crewed lunar landings. The United States remains the only nation in the world that has managed to achieve such a feat. The last moon landing mission of the Apollo program, Apollo 17, itself, was...

Ironically, the radiation drop is caused by increasing solar activity. Solar Cycle 25 hasroared to lifefaster than forecasters expected. The sun's strengthening and increasingly tangled magnetic field repels cosmic rays from deep space. In addition, solar coronal mass ejections (CMEs) sweep aside...
The moon is a bit more than one-fourth (27%) the size of Earth, a much larger ratio (1:4) than any other moons to their planets. This means the moon has a great effect on our planet and may even be a major factor in making life on Earth possible. ...
If the Earth-size planet is confirmed, it will become the smallest planet yet that TESS has found in a habitable zone. The search for Earth-like planets Red dwarf stars are the most common stars in our galaxy, and a number of them have been found to host small, rocky worlds, such as...
