Yes, 'diamond rain' on Uranus and Neptune

Despite their size, Uranus and Neptune are seldom mentioned; all the media attention goes to their larger siblings, Jupiter and Saturn.  In the beginning, Uranus and Neptune appear to be bland, boring balls of indifferent molecules. There may be something spectacular lying beneath the outer layers of these worlds: an endless rain of diamonds. In fact, astronomers refer to Uranus and Neptune as ice giants, rather than Tolkien-like creatures. In spite of this, the name refers to nothing like ice in the sense that you would usually think of it - as in ice cubes in drinks. The distinction comes from what these planets are made of. Mercury and Venus are small, rocky planets. Jupiter and Saturn are giant gas giants. This vast planet was able to swell to its present size due to the rapid accretion of those elements. Neptune, on the other hand, is mostly made up of methane, ammonia, and water. These molecules are commonly referred to as "ice" by astronomers, but there's no real r...

The mirrors of James webb telescope

how were mirrors formed in james webb telescope The mirrors of the James Webb telescope are the biggest and most complex mirrors built to date. The telescope consists of 18 HEXAGONAL mirrors. These mirrors will look at those regions of the cosmos that no other telescope in the past could. They will show us how the cosmos looked just 200 million years after the big bang and will help us understand the formation of the first galaxies. But how Exactly is Webb going to achieve that? What is it so special about the 18 hexagonal mirrors of the telescope that make it the most incredible space telescope humans have built to date? For any telescope out there, the primary mirror is like its heart the primary mirror is the one that captures all the light from distant sources and this light is further processed to produce breathtaking images of the cosmos, wonders beyond us. However, this is possible if only the mirrors are designed precisely. Fabricating a telescopic mirror is not a cakew...

​​What Is Ferrofluid?

Ferro fluids Explained A ferrofluid is a liquid which becomes highly magnetized in the presence of a magnetic field. The distinctive ‘spikey’ shape of a magnetized ferrofluid is caused by the need to find the most stable shape in order to minimize the total energy of the system, an effect known as the normal-field instability. The fluid is more easily magnetized than the surrounding air, so is drawn out along the magnetic field lines, resulting in the formation of peaks and troughs. However, the extension of the ferrofluid is resisted by gravity and surface tension. The formation of the corrugations lowers the magnetic energy of the system but raises the gravitational energy and surface free energy. When these forces are balanced, the minimum energy configuration is achieved. Because ferrofluids are very easily magnetized (they have an incredibly high magnetic susceptibility), the peaks can be produced using a small bar magnet. Ferrofluids are known as colloidal fluids and are compos...

How do Bluetooth devices work?

How do Bluetooth devices work? bluetooth working explained Have you ever wondered how Bluetooth devices transmit data without any wire or cable? let's find out how!  Bluetooth uses radio waves instead of wires or cables to transmit information between electronic devices over short distances. Unlike your cellphone, which uses radio waves to communicate with a cell tower several miles away, the radio waves Bluetooth products use are 1000 times weaker and only travel small distances between the two communicating devices, usually 10 feet or less.  If you have a wireless Bluetooth keyboard for your computer, and you take the keyboard to a friend’s house but leave the computer at home, your keyboard won’t be able to communicate with the computer over such a distance. And if you type on it, nothing will appear on your computer screen at home. ALSO READ : What would happen if we covered the Sahara Desert with solar panels? When Bluetooth-enabled devices are close enough, they ...

know how to download and install linux o.s in a pc or laptop!

 Installation of the Linux operating system We go to the linux download page and select the system of 64 bits or 32bits and then click on “Start Download”. Then, It will begin to download an ISO image. Once downloaded the ISO file, Insert the USB drive into the computer 🖥 and then open the Universal USB Installer application. Execute the Universal USB Installer application and select in step 1 the ISO image that u downloaded earlier, in step 2 choose the location of the ISO file that you have downloaded above and in step 3 Select the letter of the USB drive (IMPORTANT: WILL ERASE ALL DATA!!) and click on “Create”: When the process is complete, extract the USB drive safely and turn off the laptop. Connect the USB drive to the laptop loan and it turn on. As soon as the LAPTOP/PC logo appears press F12 or any boot key and when the boot menu appears choose the USB drive. The Linux installation begin automatically. Then, Select the ENGLISH language or failing, that you prefer...

SpaceX starts refunding to Indians who pre-booked Starlink

  Starlink had withdrawn its pre-orders offer in India after the communications ministry missive Elon Musk's SpaceX satellite broadband arm, Starlink, has begun refunding the $99 (Rs 7,400) deposits customers who pre-booked Starlink satellite broadband connections have received. In a communication to Indian consumers who pre-ordered a Starlink connection, Starlink said it was being instructed by India's Department of Telecommunications (DoT) to refund pre-orders until it is licensed. As stated in the company's communication, customers in India who had pre-ordered Starlink were required to log into their accounts on the company's website, cancel, and request refunds. ET received a copy of Starlink's customer communication in which it said "The refund will be processed immediately, but it may take up to 10 days to appear in your account.". In a statement, Starlink said it has removed the pre-booking restriction from its upcoming broadband-from-space service ...

If photons are massless, why does light get attracted to black holes?

Photons have no rest mass. But the quantity that determines how a thing gravitates, or responds to gravitation, is not rest mass. It is a complex entity called the stress-energy-momentum tensor that consists of energy, momentum, pressure and shear stresses. (It is usually represented by a 4 times 4 symmetric matrix. It is not a simple number.) Now it so happens that for most everyday objects, their speeds are small compared to the speed of light, and pressure and stresses are also small compared to relativistic mediums. So the stress-energy-momentum tensor is dominated by rest mass. When it comes to the Sun, the Earth, a lump of metal, a human being… gravitational behavior is very accurately (but not perfectly!) described using Newtonian gravity and their respective rest masses. But the moment we get to relativistic speeds, this is no longer the case. Entities can no longer be characterized by rest mass alone; other components of the tensor become equally important. In particular, a ph...
