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.
Two Arizona State University astrophysicists, Steven Desch and Alan Jackson of the School of Earth and Space Exploration, set out to explain the odd features of 'Oumuamua and have determined that it is likely a piece of a Pluto-like planet from another solar system.

Learning lessons from the past on space debris Ten years of safer skies with Europe’s other satnav system

With 26 satellites in orbit and more than two billion receivers in use, Europe’s Galileo satellite navigation system has made a massive impact. But our continent has another satnav system that has been providing safety-of-life services for ten years now – chances are that you’ve benefited from it without noticing.
Maps to improve forest biomass estimates

Fluctuations in the carbon-rich biomass held within the world’s forests can contribute to, or slow, climate change. A series of new maps of above ground biomass, generated using space observations, is set to help our understanding of global carbon cycling and support forest management, emissions reduction and sustainable development policy goals.
Astronauts in crewed missions to Mars could misread vital emotional cues

Living for nearly 2 months in simulated weightlessness has a modest but widespread negative effect on cognitive performance that may not be counteracted by short periods of artificial gravity, finds a new study published in Frontiers in Physiology. While cognitive speed on most tests initially declined but then remained unchanged over time in simulated microgravity, emotion recognition speed continued to worsen. In testing, research participants were more likely to identify facial expressions as angry and less likely as happy or neutral.
"Astronauts on long space missions, very much like our research participants, will spend extended durations in microgravity, confined to a small space with few other astronauts," reports Mathias Basner, professor in the Department of Psychiatry at the University of Pennsylvania Perelman School of Medicine.
ISS crew once again uses tea leaves to locate air leak in Russian module Zvezda

The crew of the International Space Station (ISS) is once again using tea leaves to find an air leak in three possible locations in the Russian Zvezda module, according to a communication of the crew with Earth, broadcast by NASA.
A specialist from the Russian Mission Control Center told cosmonaut Sergey Ryzhikov that thin strips of paper that were released in the module's access section e New study challenges long-held theory of fate of Martian Water

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.

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.

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
