Is Life inside Enceladus? Cassini Uncovers Complex Organic Chemistry in Saturn’s Ocean Moon
A fresh analysis of old data has found rich organic chemistry within the hidden ocean of Saturn’s moon Enceladus
Cassini proves complex chemistry in Enceladus ocean
Scientists digging through data collected by the Cassini spacecraft have found new complex organic molecules spewing from Saturn’s moon Enceladus. This is a clear sign that complex chemical reactions are taking place within its underground ocean. Some of these reactions could be part of chains that lead to even more complex, potentially biologically relevant molecules.
Published today in Nature Astronomy, this discovery further strengthens the case for a dedicated European Space Agency (ESA) mission to orbit and land on Enceladus.

October’s Night Sky Notes: Let’s Go, LIGO!
R. Hurt/Caltech-JPL
by Kat Troche of the Astronomical Society of the Pacific
September 2025 marks ten years since the first direct detection of gravitational waves as predicted by Albert Einstein’s 1916 theory of General Relativity. These invisible ripples in space were first directly detected by the Laser Interferometer Gravitational-Wave Observatory (LIGO). Traveling at the speed of light (~186,000 miles per second), these waves stretch and squeeze the fabric of space itself, changing the distance between objects as they pass.
Waves In SpaceGravitational waves are created when massive objects accelerate in space, especially in violent events. LIGO detected the first gravitational waves when two black holes, orbiting one another, finally merged, creating ripples in space-time. But these waves are not exclusive to black holes. If a star were to go supernova, it could produce the same effect. Neutron stars can also create these waves for various reasons. While these waves are invisible to the human eye, this animation from NASA’s Science Visualization Studio shows the merger of two black holes and the waves they create in the process.
Two black holes orbit each other, generating space-time ripples called gravitational waves in this animation. As the black holes get closer, the waves increase in until they merge completely. NASA’s Goddard Space Flight Center Conceptual Image Lab How It WorksA gravitational wave observatory, like LIGO, is built with two tunnels, each approximately 2.5 miles long, arranged in an “L” shape. At the end of each tunnel, a highly polished 40 kg mirror (about 16 inches across) is mounted; this will reflect the laser beam that is sent from the observatory. A laser beam is sent from the observatory room and split into two, with equal parts traveling down each tunnel, bouncing off the mirrors at the end. When the beams return, they are recombined. If the arm lengths are perfectly equal, the light waves cancel out in just the right way, producing darkness at the detector. But if a gravitational wave passes, it slightly stretches one arm while squeezing the other, so the returning beams no longer cancel perfectly, creating a flicker of light that reveals the wave’s presence.
When a gravitational wave passes by Earth, it squeezes and stretches space. LIGO can detect this squeezing and stretching. Each LIGO observatory has two “arms” that are each more than 2 miles (4 kilometers) long. A passing gravitational wave causes the length of the arms to change slightly. The observatory uses lasers, mirrors, and extremely sensitive instruments to detect these tiny changes. NASAThe actual detection happens at the point of recombination, when even a minuscule stretching of one arm and squeezing of the other changes how long it takes the laser beams to return. This difference produces a measurable shift in the interference pattern. To be certain that the signal is real and not local noise, both LIGO observatories — one in Washington State (LIGO Hanford) and the other in Louisiana (LIGO Livingston) — must record the same pattern within milliseconds. When they do, it’s confirmation of a gravitational wave rippling through Earth. We don’t feel these waves as they pass through our planet, but we now have a method of detecting them!
Get InvolvedWith the help of two additional gravitational-wave observatories, VIRGO and KAGRA, there have been 300 black hole mergers detected in the past decade; some of which are confirmed, while others await further study.
While the average person may not have a laser interferometer lying around in the backyard, you can help with two projects geared toward detecting gravitational waves and the black holes that contribute to them:
- Black Hole Hunters: Using data from the TESS satellite, you would study graphs of how the brightness of stars changes over time, looking for an effect called gravitational microlensing. This lensing effect can indicate that a massive object has passed in front of a star, such as a black hole.
- Gravity Spy: You can help LIGO scientists with their gravitational wave research by looking for glitches that may mimic gravitational waves. By sorting out the mimics, we can train algorithms on how to detect the real thing.
You can also use gelatin, magnetic marbles, and a small mirror for a more hands-on demonstration on how gravitational waves move through space-time with JPL’s Dropping In With Gravitational Waves activity!

Constraining Proxima b’s Atmosphere, Orbit, and Albedo with RISTRETTO
What new methods can be employed to help astronomers distinguish the light from an exoplanet and its host star so the former’s atmosphere can be better explored? This is what a recent study accepted to Astronomy & Astrophysics hopes to address as an international team of researchers investigated how a novel and proposed telescopic instrument that could be capable of characterizing exoplanet atmospheres in new and exciting ways. This study has the potential to help scientists develop novel tools for examining exoplanets and whether they could possess life as we know it, or even as we don’t know it.
Behold the JWST's Stunningly-Detailed Images of the Largest Star-Forming Cloud in Milky Way

NASA is Looking to Launch Artemis II by February
NASA announced that Artemis II, the first crewed mission to the Moon since the Apollo Era, will launch by February 2026. The crew has named their spacecraft "Integrity" to honor the efforts those working tirelessly to realize NASA's long-awaited return to the Moon.
Setting Bounds On SETI
The Search for Extraterrestrial Intelligence (SETI) has a data scale problem. There are just too many places to look for an interstellar signal, and even if you’re looking in the right place you could be looking at the wrong frequency or at the wrong time. Several strategies have come up to deal narrow the search given this overabundance of data, and a new paper from Naoki Seto of the Kyoto University falls nicely into that category - by using the Brightest Of All TIme (BOAT) Gamma Ray Burst, with some help from our own galaxy.

NASA, International Partners Deepen Commitment to Artemis Accords
NASA, along with leaders from global space agencies and government representatives worldwide, convened on Monday to further the implementation of the Artemis Accords — practical principles designed to guide the responsible exploration of the Moon, Mars, and beyond.
The meeting was held during the 76th International Astronautical Congress (IAC) taking place in Sydney. In opening remarks, acting NASA Administrator Sean Duffy highlighted the five-year anniversary of the Artemis Accords next month.
“When President Trump launched the Artemis Accords in his first term, he made sure American values would lead the way – bringing together a coalition of nations to set the rules of the road in space and ensure exploration remains peaceful. After five years, the coalition is stronger than ever. This is critical as we seek to beat China to the Moon, not just to leave footprints, but this time to stay,” said Duffy.
The United States, led by NASA and the U.S. Department of State, signed the accords on Oct. 13, 2020, with seven other founding nations. The accords were created in response to the growing global interest in lunar activities by governments and private companies. They now comprise 56 country signatories — nearly 30% of the world’s countries.
The event was co-chaired by NASA, the Australian Space Agency, and the UAE Space Agency. Dozens of nations were represented, creating the foundation for future space exploration for the Golden Age of exploration and innovation.
“Australia is a proud founding signatory of the Artemis Accords and is focused on supporting new signatories in the Indo-Pacific region,” said Head of Australian Space Agency Enrico Palermo. “The purpose of the accords is as important — if not more important — as it was when first established. This annual gathering of principals at IAC 2025 is a key opportunity to reaffirm our collective commitment to exploring the Moon, Mars and beyond in a peaceful, safe, and sustainable way.”
During the meeting, leaders discussed recommendations for non-interference in each other’s space activities including transparency on expected launch dates, general nature of activities, and landing locations. They also discussed orbital debris mitigation and disposal management, interoperability of systems for safer and more efficient operations, and the release of scientific data.
In May 2025, the United Arab Emirates hosted an Artemis Accords workshop focused on topics, such as non-interference and space object registration and reporting beyond Earth orbit.
“Through our active participation in the Artemis Accords and by organizing specialised workshops, we aim to reinforce the principles of transparency, sustainability, and innovation in space activities. We are committed to strengthening international partnerships and facilitating the exchange of expertise, thereby contributing to the development of a robust global framework for safe and responsible space exploration, while opening new frontiers for scientific research,” said UAE Minister of Sports and Chairman of UAE Space Agency Ahmad Belhoul Al Falasi. “This reflects the UAE’s unwavering commitment to enhancing international cooperation in space exploration and promoting the peaceful use of space.”
More countries are expected to sign the Artemis Accords in the months and years ahead, as NASA continues its work to establish a safe, peaceful, and prosperous future in space.

What’s Up: October 2025 Skywatching Tips from NASA
A supermoon takes over the sky, the Draconid meteor shower peeks through, and the Orionid meteor shower shines bright.
Skywatching Highlights- Oct. 6: The October supermoon
- Oct. 6-10: The Draconid meteor shower
- Oct. 21: The Orionid meteor shower peaks (full duration Sept. 26 – Nov. 22)
What’s Up for October? A Supermoon takes over, the Draconid meteor shower peeks through, and the Orionid meteors sparkle across the night sky.
The evening of October 6, look up and be amazed as the full moon is bigger and brighter because – it’s a supermoon!
Illustrated infographic showing the difference (as seen from Earth) between perigee, when a supermoon appears, and apogee, when a micromoon appears. NASA/JPL-CaltechThis evening, the moon could appear to be about 30% brighter and up to 14% larger than a typical full moon. But why?
Supermoons happen when a new moon or a full moon coincides with “perigee,” which is when the moon is at its closest to Earth all month.
So this is an exceptionally close full moon! Which explains its spectacular appearance.
And what timing – while the supermoon appears on October 6th, just a couple of days before on October 4th is “International Observe the Moon Night”!
It’s an annual, worldwide event when Moon enthusiasts come together to enjoy our natural satellite.You can attend or host a moon-viewing party, or simply observe the Moon from wherever you are.
So look up, and celebrate the moon along with people all around the world!
The supermoon will light up the sky on October 6th, but if you luck into some dark sky between October 6th and 10th, you might witness the first of two October meteor showers – the Draconids!
The Draconid meteor shower comes from debris trailing the comet 21P Giacobini-Zinner burning up in Earth’s atmosphere
These meteors originate from nearby the head of the constellation Draco the dragon in the northern sky and the shower can produce up to 10 meteors per hour!
The Draconids peak around October 8th, but if you don’t see any, you can always blame the bright supermoon and wait a few weeks until the next meteor shower – the Orionids!
Sky chart showing the Draconid meteor shower, including the radiant point of the shower and the Draco constellation where the meteors in the shower are often seen and stem from. NASA/JPL-CaltechThe Orionid meteor shower, peaking October 21, is set to put on a spectacular show, shooting about 20 meteors per hour across the night sky.
This meteor shower happens when Earth travels through the debris trailing behind Halley’s Comet and it burns up in our atmosphere.
The full duration of the meteor shower stretches from September 26 to November 22, but your best bet to see meteors is on October 21 before midnight until around 2 am.
Sky chart showing the Orionid meteor shower, including the radiant point of the shower and the Orion constellation where the meteors in the shower are often seen and stem from. NASA/JPL-CaltechThis is because, not only is this night the shower’s peak, it is also the October new moon, meaning the moon will be between the Earth and the Sun, making it dark and invisible to us.
With a moonless sky, you’re much more likely to catch a fireball careening through the night.
So find a dark location after the sun has set, look to the southeast sky (if you’re in the northern hemisphere) and the northeast (if you’re in the southern hemisphere) and enjoy!
Orionid meteors appear to come from the direction of the Orion constellation but you might catch them all across the sky.
Here are the phases of the Moon for October.
