Galaxy-wide echoes from the past

Astronomers have identified a new class of galaxies, known as green beans, which are rare and display the largest and brightest glowing regions ever found. These giant glows are thought to be echoes from when the central black hole was more active in the past, providing valuable insights into galaxy evolution.

First temperate exoplanet sized up

Astronomers have discovered a temperate exoplanet, Corot-9b, with a mass about 80% that of Jupiter and an orbit similar to Mercury's. The planet is thought to have a temperature range of -20°C to 160°C, making it a significant finding in the study of exoplanets.

World's observatories watching 'cool' star

Scientists are synchronizing lenses of the Whole Earth Telescope network to monitor a white dwarf, shedding light on its composition and applying knowledge to Earth's weather. The star, WDJ1524-0030, is losing brightness as it cools, with astronomers studying its pulses to understand internal movements.

Cosmic ray mystery solved?

A study by scientists has found that the most energetic particles in the universe – ultrahigh-energy cosmic rays – are correlated with the centers of active galaxies hosting violent black holes. The sources are thought to be within 326 million light years, our local neighborhood in cosmic terms.

Biggest 'small' black hole discovered

Researchers at Yale University have discovered a massive stellar black hole, located in a distant galaxy, which challenges the current understanding of how these objects form. The black hole has a mass of 15.65 times that of the sun and was detected using precise measurements of its gravitational effects on nearby stars.

NSF renews Cornell's Arecibo contract

The National Science Board has awarded Cornell University a $70 million contract to manage the Arecibo Observatory until March 31, 2010. This renewal will enable further scientific research capabilities at the observatory, with plans to develop new instruments and expand user access.

Spitzer Space Telescope finds bright infrared galaxies

A Cornell University-led team has discovered a mysterious population of distant galaxies radiating in the infrared spectrum with hundreds of times more power than our Milky Way galaxy. The galaxies are thought to be ultraluminous infrared galaxies powered by massive starbursts or active galactic nuclei, and their discovery is published...
