Is the Earth not a perfect sphere? The true form of the 'geoid' shaped by rotation and gravity｜orionfield
1+ day, 12+ hour ago (382+ words) The Earth we live on looks like a beautiful blue sphere when viewed from outer space. However, from the strict perspective of geodesy and geophysics, the Earth is not a perfect 'true sphere.' In reality, it has a shape called…...
When Hubble swings from one galaxy to another, engineers fire no thrusters—Hubble has none. They change the speeds of four internal reaction wheels, making the observatory rotate the opposite way, while magnetic bars push against Earth’s field to bleed off excess momentum: a propellant-free steering system used since 1990.
1+ hour, 3+ min ago (634+ words) Hubble turns by trading angular momentum with four internal reaction wheels, then uses magnetic torquer bars to unload the momentum those wheels accumulate....
Earth’s centre of mass wanders several millimetres relative to the solid planet over the course of each year, as monsoon rains, snowpack, ocean water and shifting air masses redistribute weight around the globe.
3+ hour, 6+ min ago (1314+ words) A new geodetic analysis combines satellite ranging, GPS and orbital data to trace the millimetre-scale annual offset between Earth's mass centre and its solid surface....
The Little-Known Ukraine Who Imagined and Calculated the Moon Landing
4+ hour, 24+ min ago (708+ words) In brief: A self-taught Ukrainian helped the Americans land on the Moon and Soviet scientists were left kicking themselves. He also calculated the optimal Earth-Moon trajectory for a spaceship and mathematically substantiated the concept of using a gravitational maneuver. Four…...
What Is Humanity’s Place in the Cosmos?
4+ hour, 34+ min ago (1467+ words) A lifelong fascination with terra incognita led the astrophysicist Priyamvada Natarajan to map out the universe’s most enigmatic phenomena....
NASA, SpaceX target early October launch as Crew-13 head into quarantine
1+ day, 13+ hour ago (337+ words) Central Florida astronaut Luke Delaney is getting closer to his first spaceflight as he and his three Crew-13 crewmates entered quarantine Thursday night targeting a Space Coast launch in early October. They're slated to launch from Cape Canaveral Space Force…...
Where does a planet end and a star begin? Webb found a free-floating brown dwarf only about twice Jupiter’s mass, surrounded by a disk of planet-forming material — an object with a planet’s mass that appears to have formed like a star.
5+ hour, 8+ min ago (1201+ words) Webb spectroscopy identifies a roughly two-Jupiter-mass IC 348 member with infrared excess from a disk, while spatial evidence favors star-like formation over planetary ejection....
Venus to reach peak brightness in Oman’s evening sky on Tuesday
5+ hour, 23+ min ago (186+ words) MUSCAT: Venus will reach peak brightness in Oman’s evening sky on Tuesday, appearing as a brilliant point of light visible to the naked eye, even in... MUSCAT: Venus will reach peak brightness in Omanâs evening sky on Tuesday, appearing…...
Strange Seeds Appear to Be Growing Into Massive Black Holes
5+ hour, 36+ min ago (492+ words) Published Sep 20, 2026 8:00 AM EDT For years now, scientists have been puzzled by the existence of “little red dots” first showing up in observations by NASA’s James Webb Space Telescope. These objects appeared in a region they believe dates to just…...
Are you sure you’re not a Flat-Earther?
2+ hour, 5+ min ago (203+ words) Let’s start with the obvious question: Do you think the earth is flat? I’m going to make the assumption that because you’re on Medium you’re of an …...
