X-ray and UV emissions impact Cygnus OB2’s protoplanetary disks, astronomers suggest | Sci.News

Cygnus OB2 is the young massive stellar association closest to our Sun. In this new composite image, Chandra data (purple) show diffuse X-ray emission and young stars in Cygnus OB2, and infrared data from NASA’s now-retired Spitzer Space Telescope (red, green, blue and cyan) reveal young stars. and colder dust and gases throughout the region. … Read more

Carbon sources spotted in cold interstellar clouds

Carbon sources spotted in cold interstellar clouds

To help understand the emergence of life on Earth, some scientists are trying to unravel the cosmic carbon cycle. The interstellar chemistry of polycyclic aromatic hydrocarbons (PAHs), a large family of carbon-containing molecules found in space, is an interesting starting point. Although these many-ringed molecules are abundant in the swirling gas in the interstellar medium, … Read more

SpaceX, which owns most satellites, could join space debris charter

By Alimat Aliyeva The European Space Agency (ESA) is in talks with Elon Musk’s SpaceX about joining an international charter to reduce the growing amount of debris in space, Azernews reports. ESA, which currently brings together 22 countries, is actively involved in efforts to reduce the mass of space debris thrown into the planet’s orbit … Read more

Selfish DNA is not only harmful, but plays a vital role in embryo development

Selfish DNA is not only harmful, but plays a vital role in embryo development

Study finds that transposable elements, once thought to be parasitic, are crucial for early human development. Sinai Health researchers have shown that these genomic segments, called “selfish DNA”, in particular LINE-1, actively contribute to the proper formation of human embryos. Historically considered harmful, these elements represent approximately 20% of the human genome, while our functional … Read more

JWST spots isolated quasars powered by supermassive black holes

JWST spots isolated quasars powered by supermassive black holes

Astronomers have discovered something surprising when they went back 13 billion years into the past using the James Webb Space Telescope (JWST). They spotted supermassive quasars powered by black holes that appear to float in isolation. This is strange because, according to current theories, black holes must be surrounded by a lot of matter to … Read more
