In 1838, Friedrich Wilhelm Bessel won the race to measure the first distance to a star other than our Sun via the trigonometric parallax—setting the first scale of the universe. Recently, Mark Reid ...

Explore the impact of the LIGO discovery of gravitational waves, marking a new era in gravitational wave astronomy. The first serious attempt to measure parallax was likely Robert Hooke’s in 1669 and ...

(Nanowerk News) In 1838, Friedrich Wilhelm Bessel won the race to measure the first distance to a star other than our Sun via the trigonometric parallax – setting the first scale of the Universe.

Cambridge, MA – The Perseus spiral arm – the nearest spiral arm in the Milky Way outside the Sun’s orbit – lies only half as far from Earth as some previous studies had suggested. An international ...

Astronomers directly measured the distance to a region on the far side of our Milky Way Galaxy, past the Galaxy's center. Bill Saxton, NRAO/AUI/NSF; Robert Hurt, NASA Using a 180-year-old technique ...

Astronomers from the U.S. Naval Observatory (USNO), in collaboration with others from the REsearch Consortium On Nearby Stars (RECONS), have determined new distances to a group of faint young stars ...

Astronomical distances are best measured by trigonometric parallax — using the annual shift in star position caused by Earth's motion around the Sun to derive distance. Now James Miller-Jones of the ...
