The Hubble Space Telescope has revealed a glittering treasure trove of more than 800,000 stars and protostars embedded inside the Tarantula Nebula. The observations were obtained as part of the Hubble Tarantula Treasury Program, which will produce a large catalog of stellar properties.
The Hubble Space Telescope observed a 'light echo' phenomenon as RS Puppis variable star pulsed, measuring its distance to 6,500 light-years with high accuracy. The star's fluctuations and reflected light allowed astronomers to narrow down the distance using light echoes.
The Cat's Paw Nebula is forming stars at an unprecedented rate of 200,000 suns' worth of material, with over 2,000 extremely young and still trapped inside their dusty cocoons. The cause of this 'mini-starburst' remains unclear, but its proximity to Earth makes it an ideal target for detailed study.
The iconic Horsehead Nebula is seen in a new infrared image from NASA's Hubble Space Telescope, showcasing its ethereal and transparent appearance at this wavelength. The nebula, located about 1,500 light-years away, is part of the Orion Molecular Cloud and is being formed by massive stars.
