15 new planets hint at 'traffic jam' of moons in habitable zone

08.01.2013
Volunteers from the Planethunters.org website, part of the Oxford University-led Zooniverse project, have discovered 15 new planet candidates orbiting in the habitable zones of other stars.

Added to the 19 similar planets already discovered in habitable zones, where the temperature is neither too hot nor too cold for liquid water, the new finds suggest that there may be a 'traffic jam' of all kinds of strange worlds in regions that could potentially support life.

Rather than being seen directly, the new planet candidates were found by Planethunters.org volunteers looking for a telltale dip in the brightness as planets pass in front of their parent stars. One of the 15, a Jupiter-sized planet orbiting a Sun-like star, has been officially confirmed as a planet (with 99.9% certainty) after follow-up work with the Keck telescope in Hawai'i and has been named 'PH2 b'. It is the second confirmed planet to be found by Planethunters.org.

A report of the research has been submitted to the Astrophysical Journal and is released via arxiv.org on Monday 7 January 2013.

'There's an obsession with finding Earth-like planets but what we are discovering, with planets such as PH2 b, is far stranger,' said Zooniverse lead Dr Chris Lintott of Oxford University. 'Jupiter has several large water-rich moons - imagine dragging that system into the comfortably warm region where the Earth is. If such a planet had Earth size moons, we'd see not Europa and Callisto but worlds with rivers, lakes and all sorts of habitats - a surprising scenario that might just be common.'

Planethunters lead scientist Professor Debra Fisher of Yale University said: 'We are seeing the emergence of a new era in the Planet Hunters project where our volunteers seem to be at least as efficient as the computer algorithms at finding planets orbiting at habitable zone distances from the host stars. Now, the hunt is not just targeting any old exoplanet - volunteers are homing in on habitable worlds.'

Lead author Dr Ji Wang, also of Yale University, said: 'We can speculate that PH2 b might have a rocky moon that would be suitable for life. I can't wait for the day when astronomers report detecting signs of life on other worlds instead of just locating potentially habitable environments. That could happen any day now.'

More than 40 volunteers are acknowledged in the paper for their contributions to the work. Among them is Roy Jackson, a 71-year-old retired police officer who lives in Birtley, near Gateshead. He said: 'It is difficult to put into words, the pleasure, wonderment and perhaps even pride that I have in some small way been able to assist in the discovery of a planet. But I would like to say that the discovery makes the time spent on the search well worth the effort.'

Mark Hadley, an electronics engineer from Faversham, another of the Planet Hunters credited on the paper, said: 'Now, when people ask me what I achieved last year I can say I have helped discover a possible new planet around a distant star! How cool is that?'

Dr Chris Lintott said: 'These are planet candidates that slipped through the net, being missed by professional astronomers and rescued by volunteers in front of their web browsers. It's remarkable to think that absolutely anyone can discover a planet.'

Im Focus: Temperature-controlled fiber-optic light source with liquid core

In a recent publication in the renowned journal Optica, scientists of Leibniz-Institute of Photonic Technology (Leibniz IPHT) in Jena showed that they can accurately control the optical properties of liquid-core fiber lasers and therefore their spectral band width by temperature and pressure tuning.

Already last year, the researchers provided experimental proof of a new dynamic of hybrid solitons– temporally and spectrally stationary light waves resulting...

Moving into its fourth decade, AchemAsia is setting out for new horizons: The International Expo and Innovation Forum for Sustainable Chemical Production will take place from 21-23 May 2019 in Shanghai, China. With an updated event profile, the eleventh edition focusses on topics that are especially relevant for the Chinese process industry, putting a strong emphasis on sustainability and innovation.

Founded in 1989 as a spin-off of ACHEMA to cater to the needs of China’s then developing industry, AchemAsia has since grown into a platform where the latest...

Im Focus: First real-time test of Li-Fi utilization for the industrial Internet of Things

The BMBF-funded OWICELLS project was successfully completed with a final presentation at the BMW plant in Munich. The presentation demonstrated a Li-Fi communication with a mobile robot, while the robot carried out usual production processes (welding, moving and testing parts) in a 5x5m² production cell. The robust, optical wireless transmission is based on spatial diversity; in other words, data is sent and received simultaneously by several LEDs and several photodiodes. The system can transmit data at more than 100 Mbit/s and five milliseconds latency.

Modern production technologies in the automobile industry must become more flexible in order to fulfil individual customer requirements.

Im Focus: Sharp images with flexible fibers

An international team of scientists has discovered a new way to transfer image information through multimodal fibers with almost no distortion - even if the fiber is bent. The results of the study, to which scientist from the Leibniz-Institute of Photonic Technology Jena (Leibniz IPHT) contributed, were published on 6thJune in the highly-cited journal Physical Review Letters.

Endoscopes allow doctors to see into a patient’s body like through a keyhole. Typically, the images are transmitted via a bundle of several hundreds of optical...
