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!

Tree of Light ceremony on Monday

The spectacular 100ft Tree of Light in Killarney, festooned with close on 3,000 lights and topped with a giant star, will again illuminate the town this Christmas with the official switch-on date planned for Monday next, December 8.

The lighting up ceremony will take place after a community Mass in the adjacent St Mary’s Cathedral at 6.15pm and a short prayer service will mark the big switch-on.
The towering Tree of Light is a landmark giant Californian Redwood tree located just outside the main door of the Pugin-designed building.
The project is an collaboration between a sub-committee of Killarney Chamber of Tourism and Commerce and the Killarney parish and it creates a wonderful focal point in the town in the lead up to and during the festive season.
Killarney Parish Administrator, Fr Kieran O’Brien and Christmas in Killarney Chairman, Cllr Niall Kelleher extend a warm invitation to all community groups, schools, clubs and organisations, families and individuals to attend the special Mass next Monday evening or to visit the tree this Christmastime.
The feature star on the spectacular tree will take on an extra special meaning this year as it will be dedicated to the late Donal Grady, a long-serving local councillor and former Mayor of Killarney who worked diligently and passionately for the community.
Donal, who passed away in 2024, was a dedicated public representative who worked with great passion and a real sense of purpose on behalf of his loyal supporters.
Through his work as a long-serving chief fire officer in Killarney, he helped so many families at a time when they most needed assistance and reassurance and he brought a great sense of calm and responsibility to the position
The Tree of Light was first lit to mark the millennium year when it commemorated all those who lost their lives in the conflict in Northern Ireland and it was again illuminated in the mid-2000s to remember those who had been killed on Irish roads.
Since then the project is all about community and it celebrates the fact that Killarney is such a wonderful town to live in.
In the past, the star at the top of the tree has been dedicated to great community activists Johnny Hickey, Yvonne Quill, Paul Coghlan and Rena Kennelly.
