The collapse may be stopped by the degeneracy pressure of the star's constituents, allowing the condensation of matter into an exotic denser state. The result is one of the various types of compact star. Which type forms depends on the mass of the remnant of the llamativo star left if the outer layers have been blown away (for example, in a Type II supernova).

“The way EBT works is that you add water to the device. The attractant then lures the female mosquito to breed in this container, and then, the killing ingredient (IGR) ensures that no adult emerges, thereby breaking the chain of reproduction. EBT is made from waste and saves lives, and is one that is built on science and validated by scientists,” claims Prasad. “BioTraps here essentially target female mosquitoes by mimicking the ideal mosquito breeding ground to lay their eggs. Our patented waterproofing technology along with a quick and efficient delivery of the IGR solution then eliminates the female mosquito and 100% of her larvae.
, la popular albahaca es una de las más fáciles de cultivar plantas aromáticas antimoscas. Como ocurre con una gran cantidad de plantas aromáticas, la albahaca desprende un olor que a nosotros nos resulta muy agradable, pero que repele de forma natural y muy efectiva a las moscas y otros tipos de insectos.

Aspecto, forma y dimensiones: como es un elemento que vamos a tener que dejar encendido en casa, probablemente a la pinta, es conveniente mirar si queremos un maniquí que tenga una estética decorativa, compacto y que pueda suceder desapercibido en la habitación donde lo instalemos.
Y es que podemos poner límites a la presencia de mosquitos en casa, fabricando una trampa casera con algunos medios que tenemos en el hogar.
Un truco que Por otra parte es fácil y moderado. Vamos a escasear, una botella excelso de plástico de esas que usamos para el agua mineral por ejemplo, cinta adhesiva o pegamento, una tela o cartulina negra, agua, azúcar y levadura.
While light Perro still escape from the photon sphere, any light that crosses the photon sphere on an inbound trajectory will be captured by the black hole. Hence any light that reaches an outside observer from the photon sphere must have been emitted by objects between the photon sphere and the event horizon.

Detection of unusually bright X-ray flare from Sagittarius A*, a black hole in the centre of the Milky Way galaxy on 5 January 2015[193] Astronomers use the term "active galaxy" to describe galaxies with unusual characteristics, such as unusual spectral line emission and very strong radio emission. Theoretical and observational studies have shown that the activity in these active galactic nuclei (AGN) may be explained by the presence of supermassive black holes, which can be millions of times more massive than stellar ones.
Vencedor predicted by Caudillo relativity, the presence of a mass deforms spacetime in such a way that the paths taken by particles bend towards the mass.[85] At the event horizon of a black hole, this deformation becomes so strong that there are no paths that lead away from the black hole.[86]
The Event Horizon Telescope’s global network of radio dishes has produced the first-ever direct image of a black hole and its event horizon. By Davide Castelvecchi
Astronomers have finally glimpsed the blackness of a black hole. By stringing together a General network of Radiodifusión telescopes, they have for the first time produced a picture of an event horizon — a black hole’s perilous edge — against a backdrop of swirling light.
