NASA reveals details of entire new solar system that could support life

NASA held a press conference today announcing further discoveries in the field of exoplanets (planet in orbit around other stars). In the conference, NASA provided details of an exoplanet system located around a relatively close star. The star, Trappist-1, is an ultra-cool red dwarf, much smaller than our Sun and located 39 light years from Earth. The star plays host to a remarkable planetary system.

NASA has discovered seven planets in orbit around the star. All of them are rocky or earthlike planets and three of these planets are found in the habitable or Goldilocks zone. The habitable or Goldilocks zone is the region around a star where the temperature is just right to allow liquid water to exist. These three planets are all earth-size rocky worlds and the scientists have announced that one of them is likely to have a water-rich composition. What is remarkable about this discovery is that the star plays hosts to so many rocky worlds, and that so many of these worlds are earth like or rocky, and also that three of the worlds might have liquid water on their surface.

That NASA was able to discover these worlds at all is testament to the speed at which the science in this discipline is advancing. Next year will see the launch of the James Webb Space Telescope. This telescope will carry instruments on board that will allow us to probe the atmospheres of these planets, if they have atmospheres, and ascertain what they are made of. Scientists will be looking for oxygen, ozone, methane and other gasses that serve as biosignatures hinting at the presence of life on other worlds.

For the moment, we can just speculate on what the planets may hold. So, what about going out tonight and having a look. Trappist-1 is located in the constellation of Aquarius, but unfortunately the star is much smaller than the Sun and consequently much dimmer. It is impossible to see without a really large telescope.

For all those thinking of little green men, the scientists who look for extraterrestrial life (SETI) have already pointed their radio telescopes at the system, but have found nothing. Even if we sent a signal to the planets, we would have to wait almost 80 years for any response!

Grady demands Killarney traffic review

Published

Killarney councillor Martin Grady has called for an urgent review of traffic management across the town following severe delays along the Muckross Road during the morning rush hour.

Constituents living along Muckross Road, Woodlawn, and outer Muckross areas raised serious concerns with the local representative, reporting that motorists now face delays of over 30 minutes to travel from Flesk Bridge or Woodlawn Cross into Killarney town.


The situation is causing major disruption for parents doing school runs and commuters traveling to work every morning.


“This level of congestion is simply not acceptable,” said Cllr Grady. “I have been contacted by constituents who are experiencing significant delays every morning, with parents trying to get their children to school and people trying to commute into work being caught in traffic for prolonged periods.”


Cllr Grady urged Kerry County Council to look closely at the operation and light sequencing along the route.


“I am calling for a review of the traffic situation along the Muckross Road, including the operation and sequencing of the traffic lights and whether there are any other obstructions or traffic management issues contributing to the delays,” he said.


He stressed that the gridlock is not isolated to one approach road, but affects the entire urban area as population and traffic volumes continue to rise year on year.


“But this issue goes beyond the Muckross Road. Killarney as a whole is experiencing increasing levels of traffic congestion across the town. The people of Killarney have been suffering with traffic for far too long, and the situation is getting worse,” Cllr Grady said.


“Our population is growing and traffic volumes are increasing year on year. We need to look at the bigger picture and develop a proper traffic management plan for Killarney. We need to identify where the problems are, examine how traffic is being managed across the town and put measures in place to improve traffic flow. The current situation has gone beyond what is acceptable for residents, commuters and visitors to Killarney.”
