Billions of years ago, according to geological evidence, abundant water flowed across Mars and collected into pools, lakes, and deep oceans. New NASA-funded research shows a substantial quantity of its water - between 30 and 99% - is trapped within minerals in the planet's crust, challenging the current theory that due to the Red Planet's low gravity, its water escaped into space.

In a comment published in Nature Astronomy, Dr. Nathalie Cabrol, Director of the Carl Sagan Center for Research at the SETI Institute, challenges assumptions about the possibility of modern life on Mars held by many in the scientific community.
As the Perseverance rover embarks on a journey to seek signs of ancient life in the 3.7 billion years old Jezero crater, Cabrol theorizes that not Juno reveals dark origins of one of Jupiter's grand light shows

New results from the Ultraviolet Spectrograph instrument on NASA's Juno mission reveal for the first time the birth of auroral dawn storms - the early morning brightening unique to Jupiter's spectacular aurorae.
These immense, transient displays of light occur at both Jovian poles and had previously been observed only by ground-based and Earth-orbiting observatories, notably NASA's Hubble SwRI researcher theorizes worlds with underground oceans support, conceal life

One of the most profound discoveries in planetary science over the past 25 years is that worlds with oceans beneath layers of rock and ice are common in our solar system. Such worlds include the icy satellites of the giant planets, like Europa, Titan and Enceladus, and distant planets like Pluto.

In 2017, the first interstellar object from beyond our solar system was discovered via the Pan-STARRS astronomical observatory in Hawaii. It was named 'Oumuamua, meaning "scout" or "messenger" in Hawaiian. The object was like a comet, but with features that were just odd enough to defy classification.

Using light from the Big Bang, an international team led by Cornell University and the U.S. Department of Energy's Lawrence Berkeley National Laboratory has begun to unveil the material which fuels galaxy formation.

Looking up at the starry sky, the deep Universe appears quiet and mysterious. It is hard to imagine that the ancient dwarf galaxy Enceladus violently collided and was torn apart by our own Milky Way Galaxy, leaving behind the cries of a whole new generation of children from the hundred-handed giant.

Today Roboze, a manufacturer of industrial 3D printing technology for extreme end-use applications, announced it has been selected by the University of Colorado Boulder to optimize the design and 3D printed components for a CubeSat project within the college's department of Aerospace Engineering Sciences. The CubeSat will spend at least six months in orbit measuring electromagnetic waves emitted Cosmic lens reveals faint radio galaxy

Radio telescopes are the world's most sensitive radio receivers, capable of finding extremely faint wisps of radio emission coming from objects at the farthest reaches of the universe. Recently, a team of astronomers used the National Science Foundation's Karl G. Jansky Very Large Array (VLA) to take advantage of a helping hand from nature to detect a distant galaxy that likely is the faintest r Lightning strikes played a vital role in life's origins on Earth

Lightning strikes were just as important as meteorites in creating the perfect conditions for life to emerge on Earth, geologists say.
Minerals delivered to Earth in meteorites more than 4 billion years ago have long been advocated as key ingredients for the development of life on our planet.
Scientists believed minimal amounts of these minerals were also brought to early Earth throu Congressional Democrats urge Biden to cut defense spending

WASHINGTON — Loft Orbital is buying antennas for an upcoming mission from French provider Anywaves, a deal the companies see as a sign of a growing European ecosystem of space startups.
Anywaves announced March 16 it sold two S-band antennas to Loft Orbital, which will install them on its YAM-3 spacecraft launching in June on a SpaceX Falcon 9 rideshare mission.

ESA astronaut Thomas Pesquet will serve as commander of the International Space Station towards the end of his second mission, called Alpha, currently slated to begin on 22 April this year. The announcement was made during today’s press briefing.
Thomas will be the fourth European to hold the post of commander, after ESA astronauts Frank De Winne, Alexander Gerst and Luca Parmitano. During the briefing, Thomas remarked how three back-to-back European commanders underscores the growing role of Europe in space exploration and is a testament to the hard work of ESA colleagues.
‘I am unbelievably humbled and honoured’, said Thomas.
