Abstract: The common practice in luminosity calibration of sample truncation according to relative parallax error λ can lead to bias with indirect methods such as ...

A way of estimating more accurate distances to the thousands of so-called "planetary nebulae" dispersed across our Galaxy has just been announced by a team of three astronomers based at the University ...

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 ...

Abstract: We present the first measurement of the trigonometric parallax of water masers associated with a Mira star, FV Bootis (FV Boo) using VLBI Exploration of Radio Astrometry (VERA). Based on our ...

Last week, we began a history of attempts to map the Milky Way by determining the distances to stars. We started with second century BCE astronomer Hipparchus, who successfully calculated the moon’s ...

The most accurate catalogue of the distances to more than 100,000 stars has just been released. Cambridge astronomer Dr Floor van Leeuwen has spent the past 10 years checking and recalculating data ...

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. Astronomers from the U ...
