Researchers have found among the first and perhaps only hard evidence that simple protein catalysts - essential for cells, the building blocks of life, to function - may have existed when life began.
According to a recent study, space dust could be what brought life molecules to Earth. This same mechanism could be responsible for the distribution of life throughout the Universe.
Could the building blocks for life on Earth have been delivered by meteorites crashing into ponds of water 4 billion years ago?
A team of scientists reports that it has discovered the existence of a white dwarf star whose atmosphere is rich in carbon and nitrogen, oxygen and hydrogen. The white dwarf is approximately 200 light years from Earth and is located in the constellation Boötes.
Ingredients crucial for the origin of life on Earth, including the simple amino acid glycine and phosphorus, key components of DNA and cell membranes, have been discovered at Comet 67P/Churyumov-Gerasimenko.
Humans may feel small when contemplating the universe, but astronomers are closer than ever to at least making us feel a little less lonely thanks to a new method of measuring planetary habitability and advances in telescope technology.
