Next-Gen Refueling Spacecraft to Revitalize Satellites in Geostationary Orbit

TEHRAN (ANA)- The Southwest Research Institute (SwRI) is developing a spacecraft named Astroscale Prototype Servicer for Refueling (APS-R) as part of a $25.5 million project with the U.S. Space Force.

Zombie Stars at Milky Way’s Core Defy Time

TEHRAN (ANA)- Northwestern University’s new research using simulations of 1,000 stars around the Milky Way’s supermassive black hole, Sagittarius A*, reveals that high-speed stellar collisions lead to the formation of youthful-looking stars.

Webb Unlocks Secrets of Universe’s First Light

TEHRAN (ANA)- Utilizing data from NASA’s James Webb Space Telescope, scientists have unveiled the earliest starlight spectra, revealing low-mass galaxies’ central role in the universe’s dawn.

Astronomers Unveil Dark Matter’s Role in Galaxy Evolution

TEHRAN (ANA)- A research led by a team at the IAC has managed to confirm, for the first time using observations, the effect of dark matter on galaxy evolution.

What Is A Neutron Star?

TEHRAN (ANA)- A neutron star was formed in the last moments of the life of a very large star (with more than about eight times the mass as our Sun), when the nuclear fuel in its core eventually ran out.

Galaxies Exhibit Increasing Level of Chaos While Aging

TEHRAN (ANA)- A project led by the Australian research center ASTRO 3D has highlighted age as one of the most crucial drivers in how stars orbit within galaxies, suggesting that the arrangement of stars gets messier over time.

NASA Confirms Revolutionary Dragonfly Mission to Explore Saturn’s Moon, Titan

TEHRAN (ANA)- NASA’s Dragonfly mission, set to explore Saturn’s moon Titan, has progressed to final design and construction stages with a confirmed launch in 2028 and a budget of $3.35 billion.

NASA’s DART Impact Changed Asteroid’s Shape, Orbit

TEHRAN (ANA)- After NASA’s historic Double Asteroid Redirection Test, a JPL-led study has shown that the shape of asteroid Dimorphos has changed and its orbit has shrunk.

Mysterious Galaxy Already Dead When Universe Was Young

TEHRAN (ANA)- When a galaxy runs out of gas and dust, the process of star birth stops. That takes billions of years but, there's a galaxy out there that was already dead when the Universe was only 700 million years old, the University of Cambridge found.

Webb Space Telescope Unlocks Icy Secrets of Neptune’s Birth

TEHRAN (ANA)- Researchers studying the binary asteroid Mors-Somnus in the Kuiper Belt have used the James Webb Space Telescope to gather unique data on trans-Neptunian objects, offering new insights into the formation of Neptune and the outer solar system’s dynamics.

Iranian Scientists to Build Satellite Constellation for 2 Simultaneous Missions

TEHRAN (ANA)- Iranian researchers at a knowledge-based company active in the design and construction of sensing and telecommunication satellites are trying to make a satellite constellation that simultaneously performs two remote sensing and telecommunication missions.
