Using the Devasthal optical telescope in India, astronomers have conducted photometric observations of the globular cluster NGC 4147. The observational campaign yielded the discovery of 28 new variable stars in this cluster. ...
Russian astronomers have identified three new luminous blue variable (LBV) candidates in the star-forming galaxy NGC 4736. While one of the three newly found candidates was confirmed to be an LBV, the nature of the remaining ...
It is not unusual for swarms of small earthquakes to precede a volcanic eruption. They can reach a point of such rapid succession that they create a signal called harmonic tremor that resembles sound made by various types ...

(Phys.org) -- An earthquake in the Indian Ocean off the coast of Sumatra, Indonesia on 11th April was unusually powerful, at magnitude 8.6, for a “strike-slip” type of quake, and a new analysis of the earthquake ...
(PhysOrg.com) -- New GPS data of the 2010 earthquake that devastated parts of Chile and killed over 500 people is revealing new clues about large earthquakes such as the quake in Chile and the magnitude 9.0 earthquake that ...
With an average of four mini-earthquakes per day, Southern California's San Jacinto fault constantly adjusts to make it a less likely candidate for a major earthquake than its quiet neighbor to the east, the Southern San ...
