Variability of blazar 3C 273 examined by astronomers

Using data from space observatories and ground-based telescopes, astronomers have investigated variability of a blazar known as 3C 273. The new study, presented in a paper published July 6 on the arXiv pre-print server, sheds ...

Planets must be formed early, study finds

Scientists have found evidence that planets form in a blink of an eye on a cosmic scale. New results, obtained using the combined power of Atacama Large Millimeter/submillimeter Array (ALMA) and Very Large Array (VLA), show ...

New method to study barred spiral galaxies

Analysis of gas motion in 20 nearby spiral galaxies has revealed a clear difference between those with bars and those without bars. This suggests that already available data on gas motion can be used to study bars in spiral ...

Citizen scientists spot closest young brown dwarf disk yet

Brown dwarfs are the middle child of astronomy, too big to be a planet yet not big enough to be a star. Like their stellar siblings, these objects form from the gravitational collapse of gas and dust. But rather than condensing ...

Astronomers capture a pulsar 'powering up'

A Monash-University-led collaboration has, for the first time, observed the full, 12-day process of material spiraling into a distant neutron star, triggering an X-ray outburst thousands of times brighter than our Sun.

Extending nucleic acid memory (NAM)

Humanity is creating huge amounts of data every day, billions of emails and social media updates, new websites, documents, images, and scientific and commercial big data amounting to petabytes of storage needs and beyond. ...

In planet formation, it's location, location, location

Astronomers using NASA's Hubble Space Telescope are finding that planets have a tough time forming in the rough-and-tumble central region of the massive, crowded star cluster Westerlund 2. Located 20,000 light-years away, ...
