Like black holes, white holes have properties such as mass, charge, and angular momentum.They attract matter like any other mass, but objects falling towards a white hole would never actually reach the white hole's event horizon (though in the case of the maximally extended Schwarzschild solution, discussed below, the white hole event horizon in the past becomes a black hole event horizon in ...
Two giant holes in the Sun could create impactful space weather for Earth in early February. Recent NOAA satellite images show two coronal holes, areas on the surface of the Sun with cooler plasma ...
A halo (from Ancient Greek ἅλως (hálōs) 'threshing floor, disk') [1] is an optical phenomenon produced by light (typically from the Sun or Moon) interacting with ice crystals suspended in the atmosphere. Halos can have many forms, ranging from colored or white rings to arcs and spots in the sky.
A coronal hole at the Sun's north pole observed in soft X-ray. Coronal hole size and population correspond with the solar cycle. As the Sun heads toward solar maximum, the coronal holes move closer and closer to the Sun's poles. [4] During solar maxima, the number of coronal holes decreases until the magnetic fields on the Sun reverse.
On July 11, NASA's Solar Dynamics Observatory captured a big hole on the surface of the sun. Tom Yulsman who writes for Discover's ImaGeo blog notes that there is no reason for people to be concerned.
A photo recently released by NASA?s Solar Dynamics Observatory shows the sun with a bright glow except for a dark hole-like patch.
In order to reproduce all the known outbursts, the rotation of the primary black hole is calculated to be 38% of the maximum allowed rotation for a Kerr black hole. [10] [4] The companion's orbit is decaying via the emission of gravitational radiation and it is expected to merge with the central black hole within approximately 10,000 years. [11 ...
It also confirms that the black hole is truly huge, with a mass 6.5 billion times that of the Sun. As you might imagine, taking this picture was tricky -- it required worldwide collaboration that ...
