Methane-Filled Lakes on Titan are “Surprisingly Deep”

Methane-Filled Lakes on Titan are “Surprisingly Deep” The Cassini mission to Saturn and its moons wrapped up in 2017, when the spacecraft was sent plunging into the gas giant to meet its end. But there’s still a lot of data from the mission to keep scientists busy. A team of scientists working with Cassini data […]

TESS Just Found its First Earth-Sized World

TESS Just Found its First Earth-Sized World NASA’s new planet-hunting telescope, TESS (Transiting Exoplanet Survey Satellite), just found its first Earth-sized world. Though the Earth-sized planet, and its hot sub-Neptune companion, were first observed by TESS in January 2019, it’s taken until now to confirm their status with ground-based follow-up observations. The discovery is published […]

Lithium detected in an ancient star gives new clues for Big Bang nucleosynthesis

Lithium detected in an ancient star gives new clues for Big Bang nucleosynthesis Researchers from the Instituto de Astrofísica de Canarias (Spain) and the University of Cambridge (UK) have detected lithium (Li) in the ancient star J0023+0307, a main-sequence extremely iron-poor dwarf star about 9,450 light years away in the galactic halo. phys.org Go to […]

Planck reveals link between active galaxies and their dark matter environment

Planck reveals link between active galaxies and their dark matter environment Scientists have used the tiny distortions imprinted on the cosmic microwave background by the gravity of matter throughout the universe, recorded by ESA’s Planck satellite, to uncover the connection between the luminosity of quasars – the bright cores of active galaxies – and the […]

Five planets revealed after 20 years of observation

Five planets revealed after 20 years of observation Over 4000 exoplanets have been discovered since the first one in 1995, but the vast majority of them orbit their stars with relatively short periods of revolution. Indeed, to confirm the presence of a planet, it is necessary to wait until it has made one or more […]

Astro-Challenge: Spotting Slender Moons

Astro-Challenge: Spotting Slender Moons Up for a challenge? Some of the toughest targets for a backyard observer involve little or no equipment at all. Northern hemisphere Spring brings with it one of our favorite astronomical pursuits: the first sighting of the extremely thin, waxing crescent Moon. This unique feat of visual athletics may be fairly […]

Possible evidence of an extrasolar object striking the Earth in 2014

Possible evidence of an extrasolar object striking the Earth in 2014 A pair of researchers has found possible evidence of an extrasolar object striking the Earth back in 2014. In their paper uploaded to the arXiv preprint server, Amir Siraj and Abraham Loeb describe their study of data in the Center for Near-Earth Object studies […]

Evidence of another possible planet orbiting Proxima Centauri

Evidence of another possible planet orbiting Proxima Centauri A team of researchers studying the nearest star to our solar system, Proxima Centauri, has found possible evidence of a second planet in its system. Team members Fabio Del Sordo with the University of Crete and Mario Damasso with the Observatory of Turin gave a presentation of […]

Powerful particles and tugging tides may affect extraterrestrial life

Powerful particles and tugging tides may affect extraterrestrial life Since its discovery in 2016, planetary scientists have been excited about TRAPPIST-1, a system where seven Earth-sized rocky planets orbit a cool star. Three of the planets are in the habitable zone, the region of space where liquid water can flow on the planets’ surfaces. But […]
