Scientists have wondered whether the ocean on Europa could harbor the right conditions for life.

Jupiter has nearly 100 known moons.

The project delivers the first comprehensive spectroscopic census of nearby K-type stars.

Sebastian Carrazco-Gaxiola presented the survey results at the January 2026 meeting of the American Astronomical Society in Phoenix, Arizona.

The survey aims to identify targets where Earth-like planets could provide conditions suitable for life.

A Georgia State University astronomy graduate student, Sebastian Carrazco-Gaxiola, led a new survey of nearby K-type stars.

The X-ray flare from Sagittarius A* left an observable imprint in the surrounding gas.

Recent observations indicate that Sagittarius A* has been more active in the past on cosmic timescales.

Sagittarius A* produced a powerful X-ray flare within the last few hundred to 1,000 years.

Sagittarius A* is the supermassive black hole located at the center of the Milky Way galaxy.

The Habitable Worlds Observatory is a planned flagship space telescope designed to directly image Earth-like planets around Sun-like stars.

NASA has selected industry proposals to advance technologies for its Habitable Worlds Observatory concept.

The Habitable Worlds Observatory will analyze the atmospheres of Earth-like planets for potential signs of life.

The observatory is expected to support a broad astrophysics program.

NASA's IXPE (Imaging X-ray Polarization Explorer) has been used for the first time to study a white dwarf star.

Astronomers examined the intermediate polar EX Hydrae using IXPE's unique X-ray polarization capability.

IXPE unlocked the geometry of energetic binary systems by studying EX Hydrae.

In 2024, IXPE spent nearly one week focused on the white dwarf star system EX Hydrae.

Scientists at NJIT's Center for Solar-Terrestrial Research published findings in Nature Astronomy.

Researchers at NJIT-CSTR have pinpointed a previously unknown class of high-energy particles in the Sun's upper atmosphere.

Solar physicists have identified a key source of intense gamma rays released during violent eruptions of the Sun.

Nullschool Technologies aims to keep its operations small and flexible.

Nullschool Technologies has the goal of making Earth's weather and climate visible.

Nullschool Technologies supports the operation and development of the global weather visualization site earth.nullschool.net.

Nullschool Technologies is a one-person company.

Cameron Beccario has created a new company called Nullschool Technologies.

The rogue planet's mass measurement confirms that it is indeed a planet.

Rogue planets travel through space without orbiting a host star.

A coordinated observation campaign using space- and ground-based telescopes has yielded the first precise mass measurement of a rogue planet.

Other research focus areas include mega-constellations in low Earth orbit, methods for spectrum sharing between space and ground systems, optical wireless communication technologies, and reconfigurable intelligent surfaces that can shape radio environments to improve link quality.

The development of inter-satellite links, especially optical inter-satellite links, can raise data rates and improve immunity to interference.

Low Earth orbit constellations can provide lower-latency links and help deliver global broadband and Internet of Things connectivity.

Full integration of satellite communication with 5G/6G terrestrial networks also requires dynamic adaptation of beam coverage, robust mobility and handover procedures for users moving across beams and orbits, and routing strategies that select effective paths through multi-orbit networks.

Satellites in geostationary Earth orbit, medium Earth orbit, and low Earth orbit take on different roles including access, forwarding, and relay depending on altitude and mission profile.

The previous trajectory correction attempt was delayed in December 2025 due to low thrust observed during earlier correction efforts on one of the ESCAPADE spacecraft.

NASA's twin ESCAPADE spacecraft are on a fully synchronized path to Mars.

Mission controllers successfully performed a critical trajectory correction maneuver for the second ESCAPADE probe on January 6, 2026.

Haojing Yan and colleagues from the University of Missouri's College of Arts and Science were involved in the research.

The research was conducted using NASA's James Webb Space Telescope (JWST).

Scientists at the University of Missouri identified a small group of unusual objects in the early universe that resemble stars in images but behave like compact galaxies when analyzed in detail.

The launch extends Italy's dual-use Earth observation capability.

The launch was conducted for the Italian Space Agency and the Italian Ministry of Defense.

The satellite is operated in orbit by Teles.

Thales Alenia Space, a joint venture between Thales and Leonardo, built the satellite.

The third satellite in the COSMO-SkyMed Second Generation radar constellation was launched from Vandenberg Space Force Base in California on a SpaceX Falcon 9.

Thousands of exoplanets have been discovered to date, showing that most stars have planets larger than Earth but smaller than Neptune.

The Sun does not have a planet larger than Earth but smaller than Neptune.

Ordinary matter, or what we can see, constitutes only 5% of the universe.

Dr. Rupak Mahapatra is an experimental particle physicist at Texas A&M University.

Dark matter and dark energy make up about 95% of the universe.
