Exploring Exoplanets: Unveiling the Cosmic Tapestry Beyond Our Solar System
- The IAU has set certain criteria to define planets: that it must orbit a star, be big enough to have enough gravity to force it into a spherical shape, and be big enough that its gravity has cleared away any other objects of similar size near its orbit around the Sun. Exoplanets refer to planets orbiting stars other than the Sun and thus exist outside the solar system. The five main ways to find exoplanets are radial velocity, transit, direct imaging, gravitational microlensing, and astrometry
- Radial velocity is detected by orbiting planets that cause stars to wobble in space, changing the colour of the light astronomers observe. Astronomers have detected 1090 planets through this method
- Transit is detected by observing changes in the brightness of a star when a planet crosses in front of it. Astronomers have found 4173 exoplanets using this method, making this the most successful method
- Direct imaging involves taking pictures of exoplanets by removing the overwhelming glare of the stars they orbit. Only 77 exoplanets have been identified using this approach
- Gravitational microlensing uses a planet to act as a lens, causing a star to bend and focus its light towards Earth, thus increasing the star’s brightness. Astronomers have found 217 exoplanets through this method
- Astrometry involves a planet's orbit causing a star to wobble around in space. Merely three exoplanets have been unearthed through this method as it has extremely precise accuracy requirements
- Like the planets in our solar system, exoplanets are classified based on various characteristics including their size, composition, orbital properties, and environmental conditions
- The three most intriguing exoplanets discussed here include Proxima Centauri b, HR 8799, and M51-ULS-1b
- The discovery of exoplanets through various methods has exponentially increased our understanding of planetary formation and evolution. With each new revelation, we're reminded of the boundless wonders that await us in the uncharted territories of space
- While a few of the notable exoplanets have been discussed, there are countless more awaiting detection and exploration. Each discovery brings us closer to answering fundamental questions about the nature of planetary systems, the potential for habitability, and the existence of life beyond Earth

How a New Methodology Rewrites the Age Book for Asteroids
- Researchers at Cornell University have developed a new method for estimating the age of asteroids using dynamics.
- They applied this method to the asteroid Selam and estimated its age to be around 2-3 million years old.
- The new method has advantages over traditional methods as it doesn't require expensive spacecraft or close-up images.
- It can be applied to other binary systems and help better constrain the age of asteroids.

Super-Earth Surprise: Webb Finds Atmosphere on Rocky Exoplanet For the First Time
- A possible atmosphere surrounding the 55 Cancri e exoplanet has been detected by scientists who used NASA’s James Webb Space Telescope ; this is the most definitive evidence of an atmosphere on any rocky planet outside our solar system.
- The exoplanet's surface is covered by a bubbling ocean of lava, and is extremely hot, so it is unlikely to be habitable.
- Researchers believe that the planet's atmosphere is probably rich in carbon dioxide or carbon monoxide that may be bubbling up from the ocean of lava covering the planet’s surface.
- The planet is classified as a super-Earth, having a diameter almost twice Earth’s size and slightly greater density. The planet is attritubted to be similar to the rocky planets in our solar system.
- The team from NASA’s Jet Propulsion Laboratory (JPL) used the Near-Infrared Camera (NIRCam) and Mid-Infrared Instrument (MIRI) to measure 4- to 12-micron infrared light coming from the planet.
- The team used secondary eclipse spectroscopy, during which they measured the dip in the spectrum between 4 and 5 microns. This confirms the presence of an atmosphere containing carbon monoxide or carbon dioxide.
- The James Webb Space Telescope used by the team is an international program led by NASA with its partners, the European Space Agency (ESA) and the Canadian Space Agency.
- It is hoped that further exploration of rocky planets will be enabled by the use of the telescope’s new type of science.
- Research into additional observations of this exoplanet is continuing with the possibility of study into the conditions necessary for a habitable planet.
- This is all part of the James Webb Space Telescope's General Observers (GO) Program 1952, which is working to solve mysteries pertaining to our solar system, and planets around other stars, to unravel the complexities of our universe and our position within it.
