Reconstructing alien astronomers' view of our home galaxy's chemistry
Jun 23, 2023 (SPX)
The results provide part of the answer to the old question whether our home galaxy is special: at least when it comes to chemical composition, the Milky Way is ...
New era of exoplanet discovery begins with images of 'Jupiter's Younger Sibling'
Jun 23, 2023 (SPX)
The planet, called AF Lep b, is among the first ever discovered using a technique called astrometry; this method measures the subtle movements of a host star ov...
Evidence of the amino acid tryptophan found in space
Jun 21, 2023 (SPX)
High amounts of tryptophan were detected in the Perseus Molecular Complex, specifically in the IC348 star system, a star-forming region that lies 1000 light yea...
Searching for an atmosphere on the rocky exoplanet TRAPPIST-1 c
Jun 20, 2023 (SPX)
However, this measurement is also consistent with a barren rocky planet without any significant atmosphere. This work contributes to our understanding of how th...
Webb Rules Out Thick Carbon Dioxide Atmosphere for Rocky Exoplanet
Jun 20, 2023 (SPX)
With a dayside temperature of roughly 380 kelvins (about 225 degrees Fahrenheit), TRAPPIST-1 c is now the coolest rocky exoplanet ever characterized based on th...
Photosynthesis, key to life on Earth, starts with a single photon
Jun 15, 2023 (SPX)
The discovery solidifies our current understanding of photosynthesis and will help answer questions about how life works on the smallest of scales, where quantu...
Plate tectonics not required for the emergence of life
Jun 15, 2023 (SPX)
Plate tectonics allows heat from Earth's interior to escape to the surface, forming continents and other geological features necessary for life to emerge. Accor...
Gemini North detects multiple heavier elements in atmosphere of hot Exoplanet
Jun 15, 2023 (SPX)
WASP-76b is a strange world. Located 634 light-years from Earth in the direction of the constellation of Pisces, the Jupiter-like exoplanet orbits its host star...
Phosphate, a key building block of life, found on Saturn's moon Enceladus
Jun 15, 2023 (SPX)
Phosphorus, in the form of phosphates, is vital for all life on Earth. It forms the backbone of DNA and is part of cell membranes and bones. The new study, publ...
Planet orbiting 2 stars discovered using new technique
Jun 13, 2023 (SPX)
Circumbinary planets were once relegated to only science fiction, but thanks to data collected from NASA's Kepler mission, astronomers now know that multiple st...
Astronomers observe giant tails of helium escaping Jupiter-like planet
Jun 09, 2023 (SPX)
The planet, HAT-P-32b, is nearly twice the size of Jupiter and losing its atmosphere through dramatic jets of helium unfurling before and behind it as it travel...
Elusive planets play hide and seek with CHEOPS
Jun 09, 2023 (ESA)
These so-called mini-Neptunes are unlike any planet in our Solar System and provide a 'missing link' between Earth-like and Neptune-like planets that is not yet...
Remains of an extinct world of organisms discovered
Jun 08, 2023 (SPX)
The previously unknown "protosteroids" were shown to be surprisingly abundant throughout Earth's Middle Ages. The primordial molecules were produced at an earli...
'Hot Jupiters' may not be orbiting alone
Jun 07, 2023 (SPX)
While our Jupiter is far away from the sun, hot Jupiters are gas giant planets that closely orbit stars outside our solar system for an orbital period of less t...
Canadian NIRISS instrument on Webb maps an ultra-hot Jupiter atmosphere
Jun 01, 2023 (SPX)
A new study led by Universite de Montreal Ph.D. student Louis-Philippe Coulombe about this exoplanet, an ultra-hot gas giant 10 times more massive than Jupiter,...
One-third of galaxy's most common planets could be in habitable zone
May 31, 2023 (SPX)
To capture enough warmth to be habitable, these planets would need to huddle very close to their small stars, which leaves them susceptible to extreme tidal for...
A telescope's last view
May 31, 2023 (SPX)
In its last days, the telescope kept recording the brightness of stars as it was running out of fuel. On Oct. 30, 2018, its fuel tanks depleted, the spacecraft ...
Quest for alien signals in the heart of the Milky Way takes off
May 31, 2023 (SPX)
Such repetitive patterns could be the key to unlocking the mysteries of extraterrestrial intelligence in our galaxy. Suresh and his co-authors detail the projec...
Astronomers discover a key planetary system to understand the formation mechanism of the mysterious 'super-Earths'
May 26, 2023 (SPX)
The discovery is the result of a close collaboration between European and American universities and was made possible by the US space mission TESS (Transiting E...
The search for habitable planets expands
May 26, 2023 (SPX)
Worlds that form in this region-a disk of dust rotating around a central star from which planets may be built-could have surfaces rich in volatile carbon compou...
