Astronomers at the Carnegie Institution have found the first indications of highly complex organic molecules in the disk of red dust surrounding a distant star. The eight-million-year-old star, known as HR 4796A, is inferred to be in the late stages of planet formation, suggesting that the basic building blocks of life may be common in planetary systems. picked by AutumnLotus 8 months ago 0 comments edit related share plime.com |
University of Arizona astronomers who are probing the oxygen-rich environment around a supergiant star with one of the world's most sensitive radio telescopes have discovered a score of molecules that include compounds needed for life. picked by AutumnLotus 1 year ago 0 comments edit related share plime.com |
Organic molecules – in the form of methane – have been detected on a planet outside our solar system for the first time. The giant planet lies too close to its parent star for the methane to signal life, but the detection offers hope that astronomers will one day be able to analyse the atmospheres of Earth-like worlds. picked by AutumnLotus 6 months ago 5 comments edit related share science |
One of the largest and most luminous stars in our galaxy is a surprisingly prolific building site for complex molecules important to life on Earth, new measurements reveal. picked by DrNothing 1 year ago 2 comments edit related share plime.com |
Astronomers using the Hubble Space Telescope and W. M. Keck Observatory have found a lopsided debris disk around a young star known as HD 15115. As seen from Earth, the edge-on disk resembles a needle sticking out from the star. picked by AutumnLotus 1 year ago 2 comments edit related share plime.com |

A sniff test of water vapor spewing from Saturn's moon Enceladus shows it is gushing with organic molecules, increasing the possibility of life existing somewhere in the Saturn system. picked by AutumnLotus 5 months ago 1 comments edit related share science |
Organic compounds contain carbon and hydrogen and form the building blocks of all life on Earth. By analyzing organic material and minerals in the Martian meteorite Allan Hills 84001, scientists have shown for the first time that building blocks of life formed on Mars early in its history. Previously, scientists have thought that organic material in ALH 84001 was brought to Mars by meteorite impac... read full post picked by AutumnLotus 8 months ago 1 comments edit related share plime.com |
By studying in great detail the 'ringing' of a planet-harbouring star, a team of astronomers using ESO's 3.6-m telescope have shown that it must have drifted away from the metal-rich Hyades cluster. This discovery has implications for theories of star and planet formation, and for the dynamics of our Milky Way. picked by AutumnLotus 4 months ago 0 comments edit related share science |
Scientists are using the giant Robert C. Byrd Green Bank Telescope (GBT) to go prospecting in a rich molecular cloud in our Milky Way Galaxy. They seek to discover new, complex molecules in interstellar space that may be precursors to life. picked by AutumnLotus 2 months ago 1 comments edit related share science |
Probing a glowing bubble of gas and dust encircling a dying star, NASA's Hubble Space Telescope reveals a wealth of previously unseen structures. The object, called NGC 2371, is a planetary nebula, the glowing remains of a Sun-like star. The remnant star visible at the center of NGC 2371 is the super-hot core of the former red giant, now stripped of its outer layers. picked by AutumnLotus 6 months ago 0 comments edit related share science |

Tantalising traces of the building blocks of life have been spotted in nearby galaxies. However, working out the identity of these carbon-containing molecules, and when they became abundant, is proving tricky. picked by AutumnLotus 9 months ago 3 comments edit related share plime.com |
Now, a team of researchers working in New Mexico has found traces of life inside salty halite crystals. The discovery is "an invaluable resource for understanding the evolutionary record [of Earth] over a geological time frame." picked by AutumnLotus 3 weeks ago 0 comments edit related share science |
An unusual star may have swallowed its stellar companion and burped out a planet-forming cloud as a result, a new study reports. The star, called BP Piscium, is surrounded by a thick disc of gas and dust from which it appears to be sucking up new material at a prodigious rate. picked by AutumnLotus 6 months ago 0 comments edit related share science |
For the first time, astronomers have observed the initial phase in the formation of an earth-like planet. What astronomers observed was that a protoplanetary disk, or ring, around the binary star known as KH 15D, is composed of solid particles larger than what is usually observed in space. picked by AutumnLotus 5 months ago 0 comments edit related share science |
A primitive star has been born in the heart of a computer, revealing how the basic building blocks of life were present soon after the Big Bang some 13.7 billion years ago. Stars convert light elements such as helium and hydrogen into the heavier elements necessary for life and it has often been remarked that human beings are glorified stardust. picked by AutumnLotus 2 weeks ago 0 comments edit related share science |

Using observations from ESO's VLT, astronomers were able for the first time to reconstruct the site of a flare on a solar-like star located 150 light years away. The study of this young star, nicknamed 'Speedy Mic' because of its fast rotation, will help scientists better understand the youth of our Sun. picked by AutumnLotus 8 months ago 0 comments edit related share plime.com |
A developing star wrapped in a black cocoon of dust is seen sprouting giant jets in a new image from NASA's Spitzer Space Telescope. The stellar portrait, captured in infrared light, offers the first glimpse at a very early stage in the life of an embryonic sun-like star - a time when the star's natal envelope is beginning to flatten and collapse, and streams of gas are escaping. picked by AutumnLotus 9 months ago 0 comments edit related share plime.com |
