They studied a type of binary system where the smaller companion star orbits the larger parent star approximately once every 100 years—our nearest neighbour, Alpha Centauri, is an example of such a system.
"A system like this would be the equivalent of a second Sun where Uranus is, which would have made our own solar system look very different," said co-author Dr. Roman Rafikov from Cambridge's Department of Applied Mathematics and Theoretical Physics.
Meteor showers, bright planets to light up summer sky: museum - Focus Taiwan
Taipei, July 28 (CNA) Astronomy buffs in Taiwan can expect a month of exciting celestial events, including two meteor showers and ideal conditions for two planet viewings, starting July 30, the Taipei Astronomical Museum said Wednesday.

Tech Talk: A search for new planets, fighting dementia in women and more | Business |
With a major research university right in our backyard, a strong military presence and innovative companies throughout the metro region, there's often a plethora of interesting science, medical and technology news to be found in Southern Arizona.
Searching for new planets. A new device at the Kitt Peak National Observatory west of Tucson recently began its mission to discover planets outside of our solar system, after passing operational readiness review by NASA and the National Science Foundation.
What Planets Are Retrograde August 2021? An Astrologer Explains
Every single planet in astrology has its own personality and rules over different aspects of the human psyche. As they each move through the zodiac, they propel you forward, clashing with other planets and sparking new energy into your reality.
You've probably heard of the pesky Mercury retrograde, a time filled with miscommunication, disorganization, and awkward moments. You might even know about the forlorn Venus retrograde, which can increase the possibility of heartbreak.
Scientists Identify Moon-Forming Disk Around Planet Outside Solar System
Scientists say they have clearly identified for the first time a moon-forming area around a planet beyond our solar system.
The ring-shaped area surrounds an exoplanet called PDS 70c. An exoplanet is a planet that orbits a star outside our solar system.
Cosmic Legacy: Retired Space Telescope Reveals 'Hot Jupiter' Secrets – Exoplanet Exploration:
Among the first, and strangest, planets to be detected around other stars is a variety known as “hot Jupiters” – star-hugging, superheated giants once thought so unlikely that many scientists doubted their existence.
But 25 years later, hot Jupiters have been confirmed across the galaxy and even in our stellar neighborhood.
Far-off planet has a nursery for baby moons : Research Highlights

Astronomers gazing at a distant planet have noticed that it is surrounded by a ring of gas and dust, where newborn moons might be coalescing.
A tiny dot may be the best evidence yet that exoplanets have moons | Science News
The Atacama Large Millimeter/submillimeter Array in Chile glimpsed a dusty disk of potentially moon-forming material around a baby exoplanet about 370 light-years from Earth.
ALMA observed two planets, dubbed PDS 70b and 70c, circling the star PDS 70 in July 2019. Unlike most other known exoplanets, these two Jupiter-like worlds are still forming — gobbling up material from the disk of gas and dust swirling around their star ( SN: 7/2/18 ).
