Solar eclipse 2023

A solar eclipse occurs when the Moon passes between the Earth and the Sun, blocking some or all of the Sun's light from reaching the Earth. Depending on the alignment of the Moon and the Sun, a solar eclipse can be partial, annular, or total. A partial solar eclipse happens when the Moon covers only a part of the Sun's disk. An annular solar eclipse happens when the Moon is too far from the Earth to completely cover the Sun, leaving a ring of sunlight around the Moon. A total solar eclipse happens when the Moon completely covers the Sun, creating a dark shadow on the Earth.

On April 20, 2023, a hybrid solar eclipse will occur, meaning that it will be annular in some locations and total in others. The path of annularity will start in Indonesia and cross Papua New Guinea, Australia, Timor-Leste, and the Indian Ocean. The path of totality will start in Western Australia and cross Indonesia and East Timor. The maximum duration of annularity will be 3 minutes and 28 seconds, while the maximum duration of totality will be 1 minute and 16 seconds.

A hybrid solar eclipse is a rare phenomenon that occurs when the Earth's curvature and the Moon's distance from the Earth vary along the eclipse path. This causes some regions to see an annular eclipse and others to see a total eclipse. The last hybrid solar eclipse occurred on November 3, 2013, and the next one will occur on April 8, 2024.


To observe a solar eclipse safely, you need to use special equipment or methods that protect your eyes from the Sun's harmful rays. You should never look directly at the Sun without proper protection, as this can cause permanent eye damage or blindness. Some of the safe ways to view a solar eclipse are:

- Using a pinhole projector: This is a simple device that projects an image of the Sun onto a screen using a small hole. You can make one using a cardboard box, a sheet of paper, and a pin or needle. Cut a small hole in one side of the box and tape the paper on the opposite side. Point the hole towards the Sun and look at the paper to see an inverted image of the eclipsed Sun.

- Using solar filters: These are special glasses or lenses that block most of the Sun's light and allow you to look at it directly. You can buy them online or from reputable vendors. Make sure they are certified by ISO or CE standards and have no scratches or damages. Do not use sunglasses, binoculars, cameras, or telescopes without proper filters, as they can magnify the Sun's rays and damage your eyes.

- Using a telescope with a projection method: This is a technique that uses a telescope to project an image of the Sun onto a screen or a wall. You need to cover the telescope's eyepiece with a white card or paper and adjust the focus until you see a clear image of the Sun. Do not look through the telescope or touch any part of it during the projection, as it can get very hot.

A solar eclipse is an amazing spectacle that can inspire awe and wonder. It is also an opportunity to learn more about astronomy and our place in the solar system. If you are lucky enough to witness one, make sure you do it safely and enjoy this rare event.

Tesla cameras will monitor driver awareness

Tesla cars will now monitor drivers who use autopilot through in-car cameras. Techcrunch  repots tesla will activate the cameras located above the rearview mirror in model 3 and Y cars to check that drivers are paying attention to the road while using autopilot driver assist. It set in a message to drivers until now tesla cars relied on steering wheel sensors that detected whether drivers were holding on. But many drivers have shared their tricks to fool sensors and go hands-free. The cabin camera above your rearview mirror can now detect and alert driver inattentiveness while autopilot is engaged. Camera data does not leave the car itself which means the system cannot save or transmit information unless data sharing is enabled. Tesla said in a release note to its drivers which was shared by one Tesla owner on twitter. Another Twitter user shared a photo of the same update for their vehicle. Last year tesla activated its cabin-facing cameras installed in model 3 and y vehicles
