The solar system was formed from a protoplanetary disk consisting of gas and dust. Since the cumulative mass of all objects beyond Neptune is much smaller than expected and the bodies there mostly have inclined, eccentric orbits, it is likely that some process restructured the outer solar system after its formation. Susanne Pfalzner from the

After nearly 20 years, the record of the most distant radio galaxy ever discovered has been broken. A team led by Ph.D. student Aayush Saxena (Leiden Observatory, the Netherlands) has found a radio galaxy from a time when the universe was only 7 percent of its current age, at a distance of 12 billion light-years.

Forty-four planets in solar systems beyond our own have been discovered in one go, dwarfing the usual number of confirmations from extrasolar surveys, which is typically a dozen or less. The findings will improve existing models of solar systems, and may help researchers investigate exoplanet atmospheres. Novel techniques developed to validate the find could accelerate

A glittering host of galaxies populate this rich image taken with ESO’s VLT Survey Telescope, a state-of-the-art 2.6-m telescope designed for surveying the sky in visible light. The features of the multitude of galaxies strewn across the image allow astronomers to uncover the most delicate details of galactic structure. Whereas ESO’s Very Large Telescope (VLT)

Listening to electromagnetic waves around the Earth, converted to sound, is almost like listening to singing and chirping birds at dawn with a crackling campfire nearby. Such waves are therefore called chorus waves. They cause the Northern Lights, but also high-energy ‘killer’ electrons that can damage spacecraft. In a recent study to be published in

The origin of organic matter found in meteorites that formed during the birth of the Solar System 4.5 billion years ago may provide key clues to understanding the birth of life here on Earth. It could also help astronomers investigate the potential habitability of other solar systems. That’s according to a new study led by

For almost 10 years, astronomers have been studying a mysterious diffuse radiation coming from the centre of our galaxy. Originally, it was thought that this radiation could originate from the elusive dark matter particles that many researchers are hoping to find. However, physicists from the University of Amsterdam and the Laboratoire d”Annecy-le-Vieux de Physique Théorique

Scientists believe the solar system was formed some 4.6 billion years ago when a cloud of gas and dust collapsed under gravity possibly triggered by cataclysmic explosion from a nearby massive star or supernova. As this cloud collapsed, it formed a spinning disk with the sun in the center. Since then scientists have been able

Astronomers using the National Science Foundation’s Karl G. Jansky Very Large Array (VLA) have made the first radio-telescope detection of a planetary-mass object beyond our Solar System. The object, about a dozen times more massive than Jupiter, is a surprisingly strong magnetic powerhouse and a “rogue,” traveling through space unaccompanied by any parent star. “This

Scientists have identified a group of planets outside our solar system where the same chemical conditions that may have led to life on Earth exist. The researchers, from the University of Cambridge and the Medical Research Council Laboratory of Molecular Biology (MRC LMB), found that the chances for life to develop on the surface of
