Astronomers are using the NASA/ESA Hubble Space Telescope to study aurorae — stunning light shows in a planet’s atmosphere — on the poles of the largest planet in the solar system, Jupiter. This observation program is supported by measurements made by NASA’s Juno spacecraft, shortly to arrive at the gas giant.
Astronomers are exploring what might be described as the first astronomical observing tool, potentially used by prehistoric humans 6,000 years ago. They suggest that the long, narrow entrance passages to ancient stone tombs may have enhanced their view of the night sky, enabling them to detect the first appearance of seasonal stars during twilight.
The brightest area on Ceres, located in the mysterious Occator Crater, has the highest concentration of carbonate minerals ever seen outside Earth, according to a new study from scientists on NASA’s Dawn mission. The results suggest that liquid water may have existed beneath the surface of Ceres in recent geological time.
Las Cumbres Observatory have partnered with Asteroid Day 2016 and Universe Awareness to create a website which allows you to use a global network of robotic telescopes to take pictures of two asteroids — 2002 KL6 and 2010 NY65 — currently passing close to Earth. On the website you can join the international campaign to study and raise awareness about asteroids.
Scientists at Aberystwyth University have developed an automated method for three-dimensional tracking of massive eruptions from the Sun, called Coronal Mass Ejections (CMEs). The Automated CME Triangulation (ACT) system uses data from three space-based observatories that orbit the Sun at different locations, allowing scientists to view the Sun and CMEs from different angles.
This new image from the NASA/ESA Hubble Space Telescope shows a cosmic tadpole, with its bright head and elongated tail, wriggling through the inky black pool of space. Tadpole galaxies are rare and difficult to find in the local universe. This striking example, named LEDA 36252, was explored as part of a Hubble study into their mysterious properties — with interesting results.
Astronomers today (28 June) released spectacular new infrared images of the distant universe, providing the deepest view ever obtained over a large area of sky. The release of the Ultra-Deep Survey (UDS) represents the culmination of a project using the 3.8-metre United Kingdom Infrared Telescope (UKIRT) on Hawaii, building up more than 1,000 hours of exposure time.
Astronomers at Nottingham Trent University have developed a light, low cost system, deployable on a drone, that could help everyone monitor and control light pollution. The team, led by undergraduate student Ashley Fuller, present their work at the Royal Astronomical Society’s National Astronomy Meeting at the University of Nottingham.
Around half of the star formation in the local universe arises from minor mergers between galaxies, according to data from the Sloan Digital Sky Survey. Disruptions to the shapes of spiral galaxies, caused by interactions with their smallest neighbours, points to increased star formation. Evidence suggests that minor galactic mergers are therefore important drivers of galaxy evolution.
In 2015, Dr. David Sobral of Lancaster University led a team that found the first example of a spectacularly bright galaxy in the young universe named CR7 which may harbour first generation stars. Now, astronomers have identified a family of incredible galaxies that could shed further light on the transformation of the early universe known as the “epoch of reionisation.”
