They name La Palma the island of stars, and in April 2025, it become the epicenter for science, stargazing and track. I used to be there for STARMUS, a pageant that brings in combination Nobel Prize winners, astronauts, musicians and science lovers for a number of days of talks, performances and cosmic inspiration. But not anything ready me for the instant I first regarded up on the night time sky.
Standing upon the rooftop terrace of our lodge, within the stunning the city of Los Llanos de Aridane, I used to be in awe. The stars did not twinkle, they blazed. Despite being a long way from the high skywatching websites, the sky overhead was once a stunning dome of starlight. I eagerly reached for my telephone, anticipating a grainy blur. But to my marvel, the footage captured a sky bursting with stars and far-off mountain silhouettes etched in opposition to the night time sky.
STARMUS La Palma was once a actually particular revel in — person who surrounded me with stars each above and beside me. It was once inspiring to stroll amongst one of the vital international’s brightest minds and largest dreamers, all amassed on an island that feels as alive because the universe we got here to have fun.
La Palma — The island of stars
The transparent skies and loss of mild air pollution on La Palma, or Isla Bonita (the Beautiful Island), within the Canary Islands off the northwestern coast of Africa, make it a haven for astronomy enthusiasts. In 2007, the island become the sector’s first Starlight Reserve, a secure space dedicated to protecting the standard of the night time sky.
“The requirements for a Starlight Reserve specifically address the features, peculiarities and functions of each space, which may relate to the preservation of the conditions for astronomical observation, the conservation of nature, the integrity of nocturnal landscapes or sites of cultural heritage,” consistent with a remark at the Starlight Foundation web site.
The Gran Telescopio Canarias, the sector’s biggest single-aperture optical telescope, stands as a sentinel of medical discovery atop Roque de los Muchachos, the best level at the island at round 7,900 toes (2,426 meters).
One of essentially the most hanging portions of our seek advice from to Roque de los Muchachos, apart from the somewhat alien panorama as we drove up the mountain, was once seeing the Cherenkov Telescope Array Observatory (CTAO) taking form. Still beneath development, this next-generation facility will discover one of the vital maximum explosive phenomena within the gamma-ray universe. CTAO goals to resolve the mysteries in the back of cosmic debris, supermassive black holes or even darkish topic, as according to the professional CTAO web site. It would be the first observatory of its type to provide open get entry to to its information. “As an international observatory, the CTAO knows that sharing our knowledge only makes us stronger,” reads a remark at the website online.
The CTAO will perform throughout two websites: one within the northern hemisphere, right here on La Palma, and the opposite in Chile’s Atacama Desert. Together, they’ll host greater than 60 telescopes, making it the most important and maximum robust gamma-ray observatory on Earth. The first telescopes are anticipated to be deployed inside the following few years, with complete operations deliberate via the finish of the last decade.
La Palma eruption

La Palma no longer most effective performs a pioneering position in astronomy, but additionally serves as a stark reminder of Earth’s volatility. In 2021, the island was once shaken via a dramatic volcanic eruption that modified the panorama without end.
The Cumbre Vieja volcano on La Palma erupted from Sept. 19 to Dec. 13, 2021, with greater than 20,000 earthquakes happening within the days and weeks sooner than the eruption. More than 7,000 other people had been evacuated from their properties. Lava swallowed over 1,300 apartments, lined roads and farms, and disrupted 1000’s of lives . Yet the spirit of the island wasn’t damaged.
The resilience of La Palma lives in each rebuilt house, each replanted lawn and each one who selected to stick following the eruption. STARMUS La Palma venerated that spirit, no longer most effective via returning to this liked island and birthplace of STARMUS however via dedicating its presence to revitalization, engagement and hope.
STARMUS La Palma — Where science meets sound
STARMUS La Palma was once not anything in need of odd. Held from April 25 to 28, the pageant introduced in combination greater than 45 audio system, together with theoretical physicist Kip Thorne, former astronauts Chris Hadfield and Kathryn Thornton, and primatologist and anthropologist Jane Goodall. But it wasn’t on the subject of giant names. It was once about giant concepts and significant conversations.
One of essentially the most memorable speeches got here from Goodall herself.
“There is this indomitable spirit that people have,” Goodall mentioned throughout her keynote speech. “So many people tackling projects that seem impossible, people who won’t give up, people who do bring nature back to a place that we have destroyed.”
Goodall praised scientists the use of our superb mind to create era that may permit us to reside in solidarity with the wildlife, as an example, selection energies.
“Nature will come back,” Goodall mentioned — a easy however robust message of resilience and hope. Her phrases resonated deeply with the surroundings. In La Palma, the place the 2021 volcanic eruption devastated complete communities, indicators of restoration are actually in all places. Green shoots are pushing during the volcanic soil, and new existence is slowly reclaiming the panorama. Goodall’s message wasn’t simply metaphorical right here — it was once visual, rising, and actual.
We may make the sky invisible to the bottom if we are not cautious
Xavier Barcons, Director General of the European Southern Observatory
Meanwhile, Xavier Barcons, Director General of the European Southern Observatory, gave an eye-opening communicate in regards to the significance of darkish skies and the way giant telescopes are converting our view of the universe.
“We could make the sky invisible to the ground if we’re not careful,” Barcons mentioned throughout his lecture.
Barcons additionally highlighted the vulnerability of the sector’s most respected sky-observing location, the summit of Mount Paranal, the website online of the European Southern Observatory’s (ESO) Very Large Telescope (VLT) , which is susceptible to being blinded via mild air pollution from a deliberate renewable power venture.

Equally eye-opening was once Chema Alonso’s communicate on hacking AI. Equal portions exciting and terrifying, his phrases painted an image of a long term through which AI’s promise will have to be balanced via accountable keep watch over.
While astrophysicist and SETI pioneer Jill Tarter mentioned on the lookout for clever extraterrestrial era, how we do it, and what we’re searching for in giant to respond to the age-old query “are we alone?”
“It’s a very old question, it involves us, our place in the universe, how we came to be and how we might evolve in the future,” Tarter mentioned. “And I think it’s extraordinarily important.”
A glimpse of the following day
Throughout the week, audio system raised important questions on sky air pollution, satellite tv for pc particles and our converting surroundings. What does it imply to offer protection to the night time sky? Should it’s thought to be a human proper?
Looking up at La Palma’s pristine skies, it is onerous to imagine this type of view may disappear. And but, that is precisely what many worry. The message from STARMUS was once transparent: we want international stewardship to safeguard this herbal marvel. I see the celebs otherwise now. Not simply as issues of sunshine, however as fragile beacons. The night time sky connects us all — and it is ours to offer protection to.
As our flight took off from La Palma, the island fell away in the back of me — its black volcanic ridges, its verdant forests and a sky so impossibly stuffed with stars. I felt modified. Not simply impressed, however recalibrated. Back house, streetlights compete with the celebs. Life returns to its same old buzz. But one thing in me has shifted.
I went to STARMUS for science and track. I got here again in love with the sky, the science, and the improbable island of La Palma.
