It's #BlackFriday, but for us, it's the 2nd annual



It's #BlackFriday, but for us, it's the 2nd annual #BlackHoleFriday. Today, we'll post pics & info about black holes.
Here's a 2-for-1 special showing two black holes merging into one.

A black hole is a massive object whose gravitational field is so intense that no light (electromagnetic radiation) can escape it. When two orbiting black holes merge, a massive amount of energy is released in the form of jets. Meanwhile, the movement of these massive bodies disturbs the fabric of space-time around them, sending ripples of gravitational waves radiating outward. These waves are predicted by Einstein's theory of general relativity, but have yet to be directly detected.

In this video, we see a closer look at the center of a spiral galaxy reveals a pair of black holes locked in a death spiral. When they merge, the massive amount of energy is released in the form of jets.

Es #BlackFriday, pero para nosotros, es el segundo #BlackHoleFriday anual. Hoy, vamos a publicar fotos y información sobre los agujeros negros.

Aquí hay un especial de 2 por 1, que muestra dos agujeros negros se fusionan en uno solo.

Un agujero negro es un objeto masivo cuyo campo gravitacional es tan intenso que no hay luz (radiación electromagnética) puede escapar de ella. Cuando dos orbitan los agujeros negros se fusionan, una enorme cantidad de energía se libera en forma de chorros. Mientras tanto, el movimiento de estos cuerpos masivos altera el tejido del espacio-tiempo alrededor de ellos, enviando ondas de las ondas gravitacionales que irradian hacia fuera. Estas ondas son predichas por la teoría de la relatividad general de Einstein, pero aún no se han detectado directamente.

En este video, podemos ver una mirada más cercana en el centro de una galaxia espiral revela un par de agujeros negros encerrados en una espiral de muerte. Cuando se fusionan, la enorme cantidad de energía se libera en forma de chorros.

ATLANTIC OCEAN- Watching an Area

ATLANTIC OCEAN- Watching an Area With Sub-Tropical Low Potential
There's a large area of disturbed weather extending northward from the northeastern Caribbean Sea into the Atlantic Ocean for several hundred miles, as seen on this GOES-East satellite from today at 9:45 a.m. EST. That means a very soggy experience for parts of the Virgin Islands, the Dominican Republic and Puerto Rico today, who may see heavy rain.
The clouds and showers are associated with a weak surface trough (elongated area of low pressure) and an upper-level low.
The National Hurricane Center notes that a surface low pressure system could form in this area later today or tomorrow, and it could briefly acquire subtropical characteristics while moving northwestward. After that time, development is not expected while the disturbance moves north-northeastward and merges with a frontal zone.

NO. INDIAN OCEAN – System 91B

NO. INDIAN OCEAN – System 91B Has a Medium Chance for Development
The Joint Typhoon Warning Center gives System 91B a medium chance for development in the Northern Indian Ocean. It is centered near 12.8 north latitude and 87.8 east longitude, about 390 nautical miles southeast of Visakhapatnam, India.
Animated multispectral satellite imagery shows a monsoon depression with strong thunderstorms persisting along the western edge of low-level circulation center that appears to be organizing.
There are also bands of thunderstorms that have developed along the western quadrant of the storm. The system is dealing with moderate wind shear today. Maximum sustained surface winds are estimated at 25 to 30 knots (28.7 to 34.5 mph/46.3 to 55.6 kph). Minimum sea level pressure is estimated to be near 1004 millibars.
This visible image of the developing low pressure area was taken from the VIIRS instrument aboard NASA/NOAA's Suomi NPP satellite on Nov. 5 at 7:06 UTC (2:06 a.m. EST).
