'No radio astronomy from the ground would be possible anymore': Satellite mega-swarms are blinding us to the cosmos — and a critical 'inflection point' is approaching
Invisible radiation leaking out of private satellites, like SpaceX's Starlink spacecraft, is disrupting radio astronomers' ability to detect important signals from across the universe. If left unchecked, we could reach an "inflection point" beyond which we can no longer properly study the cosmos, researchers warn.
How many satellites could fit in Earth orbit? And how many do we really need?
The number of satellites orbiting Earth is rising fast, thanks to private companies such as SpaceX. But just how big will these "megaconstellations" become? And what problems might they cause?
How many satellites orbit Earth?
The number of satellites orbiting our planet is rising fast, thanks to private "megaconstellations" that pose various threats to space exploration and astronomy. But how big has the problem already become?
NASA signs new contract to use SpaceX's Starship — even though it keeps blowing up
SpaceX's Starship has been awarded a NASA contract that will allow it to be considered for future missions. However, recent explosive tests have shown the supersized spacecraft is still far from mission-ready.
NASA's SPHEREx telescope 'opens its eyes on the universe', taking stunning debut image of 100,000 galaxies and stars
SPHEREx's first images — containing roughly 100,000 points of light stars, galaxies and nebulae — have confirmed that the telescope is working according to its design.
'A notch above a gimmick': Experts question scientific merit of billionaire's Fram2 'space adventure' around Earth's poles
The recently launched Fram2 mission, which is funded and led by cryptocurrency billionaire Chun Wang, will attempt to grow mushrooms, test out hormone diapers and X-ray civilian astronauts. However, experts say that these novel experiments are unlikely to yield meaningful results.
'Welcome home!': NASA astronauts who spent 9 months in orbit finally back on Earth
After nine months in space, NASA astronauts Butch Wilmore and Suni Williams have splash-landed off the coast of Florida.
When will the 'stranded' NASA astronauts return to Earth?
After spending more than nine months in space, astronauts Butch Wilmore and Suni Williams are finally coming home. NASA is targeting a Tuesday evening (March 18) splashdown for the returning astronauts, if weather conditions remain favorable.
Liftoff! NASA launches SPHEREx telescope — an infrared observatory that will help JWST solve the mysteries of the universe
NASA's newly-launched SPHEREx space telescope will offer a complementary 'panoramic' view to the JWST's high resolution infrared snapshots, enabling astronomers to study some of the universe's biggest mysteries.
