Six galaxies undergo a sudden and dramatic transition

September 22, 2019

Galaxies come in a wide variety of shapes, sizes and brightnesses, ranging from humdrum ordinary galaxies to luminous active galaxies. While an ordinary galaxy is visible mainly because of the light from its stars, an active galaxy shines brightest at its center, or nucleus, where a supermassive black hole emits a steady blast of bright […]

Saturn’s ice rings are as old as the solar system

September 20, 2019

No one knows for certain when Saturn’s iconic rings formed, but a new study co-authored by a Southwest Research Institute scientist suggests that they are much older than some scientists think. The study takes a closer look at 2017 Cassini spacecraft data that inspired several research papers suggesting that the rings were formed around the […]

The most massive neutron star ever discovered is almost too massive to exist

September 17, 2019

Neutron stars the compressed remains of massive stars gone supernova- are the densest “normal” objects in the known universe. Black holes are technically denser, but far from normal. Just a single sugar-cube worth of neutron-star material would weigh 100 million tons here on Earth, or about the same as the entire human population.

Astronomers spotted the second interstellar object in our solar system

September 16, 2019

The new comet named C / 2019 Q4 (Borisov) was discovered on August 30, 2019 by Ukrainian amateur astronomer Gennady Borisov at the MARGO Observatory in Scientific, Crimea. Since its discovery, astronomers have discussed the formation of unusual cosmic rocks that do not appear to have circular or elliptical orbits.

NASA WFIRST will help unravel the fate of the universe

September 15, 2019

Scientists have discovered that a mysterious pressure dubbed “dark energy” makes up about 68% of the total energy content of the cosmos, but so far we don’t know much more about it. Exploring the nature of dark energy is one of the primary reasons NASA is building the Wide Field Infrared Survey Telescope (WFIRST), a […]

Scientists discovered the sound of a newborn black hole for the first time

September 14, 2019

If Albert Einstein’s theory of general relativity holds true, then a black hole, born from the cosmically quaking collisions of two massive black holes, should itself “ring” in the aftermath, producing gravitational waves much like a struck bell reverbates sound waves.

Water detected on extrasolar planets in the star’s habitable zone

September 14, 2019

Ever since the discovery of the first exoplanet in the 1990s, astronomers have made steady progress towards finding and probing planets located in the habitable zone of their stars, where conditions can lead to the formation of liquid water and the proliferation of life.

The black hole at the center of our galaxy seems increasingly hungry

September 14, 2019

The enormous black hole at the center of our galaxy is having an unusually large meal of interstellar gas and dust, and researchers don’t yet understand why. We have never seen anything like this in the 24 years we have studied the supermassive black hole, said Andrea Ghez, UCLA professor of physics and astronomy and […]

New models show that Titan lake is a blast crater

September 10, 2019

Using radar data from NASA’s Cassini spacecraft recently published research presents a new scenario to explain why some methane-filled lakes on Saturn’s moon Titan are surrounded by steep rims that reach hundreds of feet high. The models suggests that explosions of warming nitrogen created basins in the moon’s crust.

NASA Satellite detected a Mystery That’s Gone in a Flash

September 7, 2019

Pops of bright blue and green in this image of the Fireworks galaxy (NGC 6946) show the locations of extremely bright sources of X-ray light captured by NASA’s NuSTAR space observatory. Generated by some of the most energetic processes in the universe, these X-ray sources are rare compared to the many visible light sources in […]
