- via SPACE.comThere has been a lot of interest recently in an upcoming series of lunar eclipses that begins April 15. These are usually described as "Four Blood Moons" and taken by some to prophesy upcoming disasters.

Giant cosmic tsunami wakes up comatose galaxies
If clusters of galaxies merge, a huge shock wave can drive the birth of a new generation of stars. By Royal Astronomical Society, United Kingdom | Published: Friday, April 24, 2015. RELATED TOPICS: GALAXIES | GALAXY CLUSTERS | GALAXY MERGERS.

- A long-standing puzzle regarding the nature of disk galaxies has finally been solved by a team of astronomers using state-of-the-art theoretical models. The new study shows that groups of stars with the same age always flare as the result of massive galactic collisions. When taken all together, these flares, nested like the petals of a blooming rose, puff up the disk and constitute what astronomers call the âthickâ disk.
- Galaxies are often found in clusters, which contain many 'red and dead' members that stopped forming stars in the distant past. Now an international team of astronomers have discovered that these comatose galaxies can sometimes come back to life. If clusters of galaxies merge, a huge shock wave can drive the birth of a new generation of stars -- the sleeping galaxies get a new lease of life.
- Inside NASA's giant thermal vacuum chamber, called Chamber A, at NASA's Johnson Space Center in Houston, the James Webb Space Telescope's Pathfinder backplane test model, is being prepared for its cryogenic test. Previously used for manned spaceflight missions, this historic chamber is now filled with engineers and technicians preparing for a crucial test.
- We know of about two dozen runaway stars, and have even found one runaway star cluster escaping its galaxy forever. Now, astronomers have spotted 11 runaway galaxies that have been flung out of their homes to wander the void of intergalactic space.
- Detecting an 'earthquake' on Venus would seem to be an impossible task. But conditions in Venus' atmosphere are much more hospitable, and it is here that researchers hope to deploy an array of balloons or satellites that could detect Venusian seismic activity -- using sound.
- For the first time, a natural source of infrasonic waves of Earth has been measured directly from space -- 450 kilometers above the planet's surface.

- Albert Einstein tells us that clocks run slower the deeper they are in the gravitational potential well of a mass â the closer they are to a heavenly body, for example. This effect is described by General Relativity Theory as the gravitational red shift â it is detectable in spectral lines that shift toward the red end of the spectrum. General Relativity Theory also predicts that the rates of all clocks are equally influenced by gravitation independent of how these clocks are physically or t

- Saturn's moon Titan is the only moon in the solar system that has an atmosphere as thick as Earth's, consisting of more than 98 percent nitrogen, roughly 1.4 percent of methane, and smaller amounts of other gases. NASA's Cassini satellite has been circling Saturn since 2004, witnessing more than one-third of its 29-year orbit around the Sun, allowing it to observe the changing of the seasons. However, a new study finds that the seasons are not the only thing changing Titan's atmosphere: its chem
- Star system Tau Ceti has long been used in science fiction as a very likely place to have life due to its proximity to Earth and the star's sun-like characteristics. Since December 2012 Tau Ceti has become even more appealing, thanks to evidence of possibly five planets orbiting it, with two of these potentially residing in the habitable zone. Researchers took a closer look and determined that most likely the planets do not and cannot support life.

- Researchers can now explain how asteroids are formed. Our own planet also has its origins in the same process, a cosmic ocean of millimeter-sized particles that orbited the young sun, according to new research.
- Astronomers have made the first-ever direct detection of the spectrum of visible light reflected off an exoplanet. These observations also revealed new properties of this famous object, the first exoplanet ever discovered around a normal star: 51 Pegasi b. The result promises an exciting future for this technique, particularly with the advent of next generation instruments and future telescopes, such as the E-ELT.
- It was launched 25 years ago and has given humankind a glimpse at some of the farthest and earliest cosmic phenomenon in the observable Universe. On Friday, 24 April, the HST will celebrate exactly 25 years since it was launched.
