Our galaxy contains more than 30 billion planets and the observable universe contains more than 100 billion galaxies. As I read these numbers, I naturally have a question: are we alone?
From scientists and philosophers to writers and filmmakers, from believers to agnostics and devotees, to artists, poets and ordinary people, we have all wondered if anyone else is.
While clear signs of life have never been detected, astronomers look for answers, using a combination of astronomical, chemical, geological and biological sciences.
Isik Kanik is a Senior Research Scientist at Jet Propulsion Lab in Pasadena, California. His main research interests are astrobiology, detection techniques and laboratory spectroscopy. The new chief editor of Astrobiology, Professor Issik Kanik, says that now is the time to study the existence of life in the universe:
“Space science has developed rapidly in recent decades, combining new discoveries made through space exploration and in conjunction with laboratory and field research in terrestrial environments such as fuel, extreme space.
We have already made incredible discoveries: evidence of liquid water in nearby planetary bodies, identification of new planets outside our solar system, the discovery of a wide variety of novel microbial life forms in highly terrestrial environments and the emergence of life on Earth. New theories, to name a few. Everything seems to be waiting for more and more new sensational discoveries. “
- Thanks to the latest discoveries, NASA and other international research institutes are encouraging research in the field, and open access is the right tool to promote the delivery of results from the scientific community as objectively and quickly as possible.
- “Open access will help scientists develop new hypotheses and new perspectives in the field, which provide the basis for new scientific discoveries,” says Professor Kanik.
The new special section of Frontiers in Astrobiology, Astronomy and Space Science is now open for presentation and receives high quality articles and proposals for research topics.
The purpose of the section’s inaugural research topic is to emphasize the importance of astronomy to explore our own solar system while examining the possibility of life on Mars, Europe, Titan and Enceladus.
- The search for new planets continues.
- Exoplanetas, a new special section of Frontiers in Astronomy and Space Sciences, is now open for presentation.
A senior scientific researcher at NASA’s Ames Research Center, Dr. Directed by Steve B. Howell, this section will provide a focus for research on the discovery, characterization and understanding of planets that orbit the alien sun, as well like those who are stellar.
Search for exoplanets
- A growing scientific field with Nobel Prize recognition
- The study of exoplanets began only 25 years ago, but their scientific impact has been widely recognized, especially at the 2019 Nobel Prizes.
- The purpose of exoplanet research is to address one of the fundamental human questions about the universe: are we alone?
Dr. Howell explains: “Given the vastness of heaven, one can feel small and insignificant, or can feel a deep connection.” I think both. So, my desire, then and now, is to learn and share that knowledge. “
A platform to solve great exoplanet challenges
The mission of Exoplanets is to bring together leading scientists around the world, providing them with a platform to connect and share ideas and results.
- “The exoplanet community is more diverse than any other in astronomy and makes it incredibly vibrant, powerful and a fantastic platform of human interest.
- “We hope that global partnerships, new and substantial partnerships, without borders, and that the great scientific challenges of the exoplanet we face can be solved.”

Alma discovers rare carbon isotopes in 49-game debris discs: Using the Atacama Large Millimeter / Submillimeter Array (ALMA), astronomers have detected radio emissions from two carbon isotopes (12C and 13C) in a massive gas-rich debris disk of about 49 cm, located 186 lights A star of 40 million years – Away in the constellation of Situs.
“We found nuclear carbon gas in debris disks around 49 SETIs using observations for 10 hours with the 10-meter ASTE radio telescope in Chile,” said Dr. Astronomer, an astronomer at the National Astronomical Observatory in Japan. Aya explained to Higuchi. .
- “As a natural extension, we used ALMA to get a more detailed view and this gave us a second surprise.”
- “Carbon gas turned out to be 10 times more abundant than our previous estimate of around 49 SET.”
- The amount of nuclear carbon gas was so high that Drs. Higuchi and his colleagues detected radio signals not only from the common 12C isotope, but also in the very rare 13C form.
- “This is the first emission detection of 13 C at 492 GHz in an astronomical object, which is usually hidden behind the normal emission of 12 C,” he said.
- “The amount of 13C is only 1% of 12C, so the detection of 13C in the waste disk was completely unexpected,” said Dr. Higuchi.
- “This is clear evidence that the 49 Seti contains a surprisingly large amount of gas.”
- Astronomers offered two possible explanations for the origin of this carbon gas.
- “One is that it is the remaining gas that survived the dissipation process in the final stages of the planet’s formation,” he said.
- “However, the amount of gas around 49 SETI is comparable around very small stars in the active formation phase of the planet.”
- “There are no theoretical models that explain how much gas can persist for so long.”
“Another possibility is that the gas has been released when small objects such as comets collide. But the amount of collisions necessary to explain the large amount of gas around 49 SETs is too large to accommodate current theories. “
The findings appear in the Astrophysical Journal Letters.
