By analyzing the data from the SuperCOSMOS Hα Survey (SHS) and from the Gaia satellite, astronomers have inspected a bipolar planetary nebula designated PHR J1724-3859. Results of the study, published Nov. 19 on the arXiv ...
One of the most elegant theories about the origins of life on our planet is that it was kick-started by a delivery from outer space. This idea suggests that prebiotic molecules—the building blocks of life—were transported ...
European astronomers report the discovery of a second alien world in the TOI-1422 planetary system located some 500 light years away. The newfound exoplanet, which received designation TOI-1422 c, is nearly three times larger ...
A vast region of our solar system, called the Kuiper belt, stretches from the orbit of Neptune out to 50 or so astronomical units (AU), where an AU is the distance between Earth and the sun. This region consists mostly of ...
About 4.5 billion years ago, the most momentous event in the history of Earth occurred: a huge celestial body called Theia collided with the young Earth. How the collision unfolded and what exactly happened afterward has ...

If there is, or ever has been, life on Mars, the chances are it would exist in caves protected from the severe dust storms, extreme temperatures, and high radiation present on its surface. One place to focus our attention ...
Astronomers from Keele University in the UK have utilized NASA's planet-hunting TESS telescope to investigate a totally-eclipsing binary known as UZ Draconis. Results of the new observations, published October 31 on the arXiv ...
A new study led by researchers from Oxford University, Southwest Research Institute and the Planetary Science Institute in Tucson, Arizona has provided the first evidence of significant heat flow at Enceladus's north pole, ...
