A team of astronomers have used the European Southern Observatory's Very Large Telescope (ESO's VLT) in Chile to shed new light on planets around a nearby star, L 98-59, that resemble those in the ...

Scientists have discovered more than 4,000 alien planets since spotting the first ones orbiting a star beyond our sun back in 1992. Here's a brief rundown of the main techniques they use to find these ...

ABSTRACT A total of 597 radial velocity observations for 112 stars in the ∼1.6 Gyr old open cluster NGC 7789 have been obtained since 1979 with the radial velocity spectrometer at the Dominion ...

High-precision radial velocities of Arcturus measured on 43 occasions from 1981 through 1985 show a 500 m s⁻¹ range. This range is much larger than the external errors of our observations (typically ...

Using radial velocity measurements, an international team of astronomers has identified a second planet orbiting a nearby M-dwarf star known as Gliese 536. The newfound alien world turns out to be at ...

Getting out of the galaxy might take an antimatter engine. Future explorers departing the Milky Way will have to boost their spaceship to 0.2 per cent of the speed of light, according to a study of ...
