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!

Bright future for Muckross juniors with Sligo success

Published

While Muckross Rowing Club prepares to honour the legendary Olympic achievements of its past members this coming Sunday, the next generation of rowers proved over the weekend that the club’s future is in very capable hands.

In a historic first for the club, a massive squad of 54 junior athletes travelled to the Sligo Head of the River, returning to Killarney with an outstanding haul of seven victories.


The journey to the Garavogue River represented a significant step forward in the club’s development.


Under the guidance of ten dedicated junior coaches, the squad, ranging in age from 12 to 1, braved bitter cold and unfamiliar freshwater conditions to compete against 26 crews from top-tier clubs including Enniskillen Royal, City of Derry, and Belfast Boat Club.


For many of the young Kerry athletes, the 3km non-tidal course provided their first-ever taste of competitive racing.


A club spokesperson highlighted that the trip was designed to build resilience and provide the juniors with experience outside their usual racing circuits in Cork and Limerick.


The success in Sligo, combined with the upcoming celebration of the club’s Olympic heritage, shows a thriving rowing culture in Killarney.

With participation numbers continuing to grow, the Junior Club remains open to new members, holding training sessions every Saturday and Sunday morning at 9:00 am at the boathouse.

The Killarney Triathlon Club recently hosted a dedicated Women’s Morning to mark the continued success of its female-focused recruitment and support strategies.

The event was made possible through a specific grant from Triathlon Ireland, providing the necessary funding to invest in the club’s growing female contingent.
Statistics released by the club show a significant upward trend in participation, with female membership rising from 33% in 2023 to 41% by the end of 2025.
This growth reflects a long-term commitment to creating an inclusive environment that welcomes athletes of all abilities into the multi-sport community.
The morning began with a community-focused start at the local parkrun, where members participated in fancy dress to highlight the fun and social side of the sport.
Male members of the club also joined the festivities to show their support for the initiative.
This was followed by a transition to Nave Yoga, where athletes took part in a restorative session aimed at recovery and injury prevention.
Beyond the physical training, the event addressed critical aspects of women’s health in sport, including nutrition and hormonal health across different life stages. These discussions aimed to empower athletes with the expertise to support their training while prioritising their long-term wellbeing.
The day concluded with a social brunch at the Killarney Racecourse, allowing members to build the supportive networks that are essential in what is often perceived as an individual sport. By fostering these connections, the club continues to transition from a training group into a robust community hub.
The committee has expressed its gratitude to Triathlon Ireland for the grant, noting that such investment is vital for maintaining the momentum gained over the last three years. With a strong presence of female leaders on the current committee and a clear strategy for 2026, the club remains one of the most progressive sporting organisations in the county.
