In an unprecedented deep-space event, NASA’s Lucy spacecraft is being deliberately steered towards a close encounter with a newly discovered asteroid, suspected to be an interstellar visitor. This strategic maneuver promises to turn a routine flyby into a landmark moment for planetary science.

An unprecedented celestial event is unfolding in our solar system as the confirmed interstellar comet, 2I/Borisov, makes its journey around the Sun. AlwaysFirst brings you everything you need to know about this historic visitor, including when it will be closest to Earth and whether you can see it with your own eyes.

Forget the orbit of Pluto; the true boundary of our solar system is an invisible, shifting frontier known as the heliopause. Now, NASA is developing a mission to finally map this final cosmic coastline, a discovery that will redefine our understanding of the Sun’s domain and its protective shield against interstellar space.

Astronomers have uncovered the most massive black hole ever recorded—a cosmic behemoth weighing 36 billion times the mass of the Sun. This discovery reshapes our understanding of how these mysterious giants form and evolve in the universe.

Russian scientists have unveiled a revolutionary plasma propulsion system that could slash travel time to Mars from nine months to just 30 days. Using electromagnetic fields to accelerate hydrogen ions at unprecedented speeds, this engine promises continuous thrust—making interplanetary missions faster and safer. With a working prototype already in testing, could this be the future…

India and the US are making history today with the launch of NISAR, a cutting-edge Earth observation satellite developed by ISRO and NASA. Set to blast off from Sriharikota, this mission promises groundbreaking insights into our planet’s ecosystems, glaciers, and land shifts. Here’s everything you need to know.

In 1979, NASA’s Voyager 1 spacecraft captured an eerie symphony of plasma waves as it crossed Jupiter’s bow shock—a boundary where solar winds collide with the planet’s massive magnetosphere. This haunting recording, often called the ‘music of the spheres,’ reveals the unseen forces shaping our solar system’s largest planet. Decades later, scientists are still unraveling…

In a historic breakthrough, an Indian-led research team has become the first in the world to directly measure magnetic fields near a newborn massive star—a discovery that could reshape our understanding of stellar formation. The findings, published in The Astrophysical Journal Letters, suggest a universal mechanism behind how stars and galaxies are born.
