Precise Timing of A Black Hole Dance Captured by NASA’s Spitzer Space Telescope
Black holes have long been a mysterious and a special topic for astronomers and also to the layman. This mysterious region in space can not be seen directly …
Astronomers Captured Light from a Black Hole Coalescence
After 100 years of the Einsteins calculation and prediction of the gravitational waves, astronomers from the LIGO and Virgo collaborations finally …
Strange Black Holes In The Universe
In principle, a black hole can have any mass equal to or above about 2.2×10−8 kg or 22 micrograms.
Event Horizon, Singularity and Photon Sphere of a Black Hole
Event Horizon was referred to this region because for any object the region of an event horizon is the ultimate wall that they can cross...
Parker Solar Probe (Part-One); A Spacecraft to the Sun
With a mission to study the trace of energy that heats the corona and accelerates the solar wind, on August 12, 2018, space mission named Parker Solar Probe was launched from the lunch site Cape Canaveral, SLC37 using the Delta IV Heavy rocket.
Black Hole; A Mysterious Region in Space
A black hole is a region in a space where the gravitational pull is so strong that no object, even electromagnetic radiation like light can not escape from the region. The boundary of the region from where nothing can escape is called an event horizon.
For the First Time Astronomers Captured the Gravitational Waves from an Unevenly Sized Black Holes
On April 18, 2020, the LIGO Scientific Collaboration and the Virgo Collaboration announced one more discovery of gravitational waves from...
If We Can't see Black Holes, How are they Detected?
One way of detecting the black hole is by their gravitational influence and another way of detecting a black hole is by observing the matter falling into the black hole. Another way of detecting a black hole is by observing the matter falling into the black hole.
What is Black Hole Evaporation or the Hawking Radiation
Hawking claimed that considering the quantum phenomena, black holes are not totally black: they should glow slightly with radiation that consists of photons, neutrinos, and to a lesser extent all sorts of massive particles. This idea of Hawking solved the unsolved mystery of black hole i.e. entropy problem of the black hole.
How Hawking Radiation appears; What really happens inside Black Hole?
The idea Stephen Hawking used was when a black hole absorbs new materials using its immense gravitational pull then the entropy of those falling materials must go on adding the overall entropy of black hole.
Solar Wind Problem Finally Solved
It is crucial to understand the characteristics of the solar wind and recently this will be probed at distances unprecedentedly close to the Sun by the new Parker Solar Probe mission, named after living Eugene Newman Parker and was launched on August 12, 2018.
More Advanced Detection Technique of Gravitational Waves - LIGO Equipped with Quantum-Enhanced System but Why and How?
Overall, the new quantum squeezers have enhanced the expected detection rate by 40% at LIGO Hanford and by 50% at LIGO Livingston. On Sept. 14 of 2015, the Laser Interferometer Gravitational-wave Observatory (LIGO) recorded the first-ever Gravitational Wave.
How Advanced LIGO Works and What we can Learn from Gravitational Waves?
A gravitational wave propagating orthogonally to the detector plane and linearly polarized parallel to the 4-km optical cavities will produce the effect of lengthening one 4-km arm and shortening the other during one half-cycle of the wave; these length changes are reversed during the other half-cycle.
First image of a Black Hole (Part-Four); What Scientists Got?
The main aim of this project was to image an event horizon for the first time and to help determine if Einstein’s theory of general relativity needs any revision. The EHT team successfully imaged the black hole with distinctive and clear event horizon and also claimed their study further confirmes that the general theory of relativity is right at its place, till now.
First Image of a Black Hole (Part-Three); So Much Data and High-Tech Calibration
Though they were capable of increasing the capacity and the telescope can collect data over the cosmological distances, there also remained more challenges...
First Image of Black Hole (Part-Two); How Scientists saw the Unseen Black Hole?
To see the unseeable region from light also can't escape in the far space scientists need to have a more powerful telescope....
First Image of a Black Hole (Part-One)
April 10, 2019, news, 'Astronomers Capture the First Image of a Black Hole' was released by researchers at Event Horizon Telescope and its collaboration....
