🌟 Barnard’s Star – The Fast Mover Next Door 🌟


 

Barnard’s Star is a small red dwarf located just 6 light-years away, making it one of our closest stellar neighbors. What makes it special is its incredible speed across the sky—it shifts position faster than any other known star, a motion you can actually measure over a few decades! Despite its closeness, Barnard’s Star is so faint that you’ll need a telescope to see it.

Physically, this star is only about 14% the size of our Sun and shines just 0.04% as bright, yet it’s an astonishing 10 billion years old—more than twice the age of the Sun. Astronomers also suspect it hosts at least one exoplanet, nicknamed Barnard’s Star b, which could be a frozen “super-Earth.”

The importance of Barnard’s Star lies in what it teaches us: how ancient red dwarfs evolve, how stars move through the galaxy, and where we might search for potentially habitable worlds close to home. It’s a quiet but powerful reminder that even the faintest stars hold cosmic secrets. 🌌✨

Astronomy Python - Crab Nebula - Combine RGB channel images into One Image

Image
 In Astronomy, Image taken by cameras would be based on specific filters(channels)-Red, Green, Blue. Below are the the images taken across 3 channels. Red(Left), Green(Centre), Blue(Right) Original image credit(single image which is not shown here)- Credits: NASA, ESA, J. Hester and A. Loll (Arizona State University) Below is result after combining above 3 channel images Below is the python code used. Original Carb Nebula image is spitted    into 3 channels(as shown 3 gray images above) *************************************************** from PIL import Image # Open the red, green, and blue channel images red_channel = Image.open('E:\\astronomy_related\\rbg_one\\red.png') green_channel=Image.open('E:\\astronomy_related\\rbg_one\\green.png') blue_channel =Image.open('E:\\astronomy_related\\rbg_one\\blue.png') # Create a new RGB image result = Image.merge("RGB", (red_channel, green_channel, blue_channel)) # Save the result image result.save('E:\\astr...

Astronomy Python - Mars Planet Surface - Creating Sharpen Image from Blur Image

Image
   In Astronomy, sometimes the images send by satellite/telescope could be Blur and one would be interested to make the image Sharpe. The Kernel (it is matrix representation) is to process the image -from Blur image to Sharpe Image. Convolution Matrix, Mask, Matrix/Array are the other names given to the Kernel.                           Below is the example of Mars Surface Blur Image Image Credit: NASA/JPL-Caltech Below is the processed image which has now become  Sharpe Image   Please  open both images to see the effect.7 Below is the python code used. ****************************************************************** # load the required packages import cv2 import numpy as np # load the image into system memory image = cv2.imread('E:\\astronomy_related\\blurr_to_clear_image\\marssurface_blurr.jpg', flags=cv2.IMREAD_COLOR) # display the blurr image to the screen cv2.imshow('Mars Surface blurr...
