3I Atlas

3I Atlas

Discovery

The NASA-funded ATLAS (Asteroid Terrestrial-impact Last Alert System) survey telescope in Rio Hurtado, Chile, first reported observations to the Minor Planet Center of comet 3I/ATLAS on July 1, 2025.

Hubble captured this image of the interstellar comet 3I/ATLAS on July 21, 2025, when the comet was 277 million miles from Earth. Hubble shows that the comet has a teardrop-shaped cocoon of dust coming off its solid, icy nucleus.

How this comet got its name?

 Comets are generally named for their discoverer(s), in this case the ATLAS survey team. The letter “I” is for “interstellar,” indicating that this object came from outside our solar system. It’s the third known interstellar object, hence the “3” in the name.

Threat to Earth

Comet 3I/ATLAS poses no threat to Earth and will remain far away. The closest it will approach our planet is about 1.8 astronomical units (about 170 million miles, or 270 million kilometers). 3I/ATLAS will reach its closest point to the Sun around Oct. 30, 2025, at a distance of about 1.4 au (130 million miles, or 210 million kilometers) — just inside the orbit of Mars.

Working On

The interstellar comet’s size and physical properties are being investigated by astronomers around the world. 3I/ATLAS should remain visible to ground-based telescopes through September 2025, after which it will pass too close to the Sun to observe. It will reappear on the other side of the Sun by early December 2025, allowing for renewed observations.

Sixth Sense

Image
Sixth Senses  Sixth sense (ESP extra sensory perception)is a power of perception beyond the five senses.  It is an inner sense of guidance that can help you navigate your way through life, to better relationships, health, well-being, and success. It is a cumulative power of all your other senses - sight, sound, taste, touch, smell - that culminates in a stronger sense of inner knowing.

Neurodivergence -  Mental illness or Mad Scientist? Who Is Neurodiverse/Neurotypical? The terms "neurodivergent" and "neurodiverse" refer to people whose thought patterns, behaviors, or learning styles fall outside of what is considered "normal," or neurotypical of humans. The concept of neurodiversity is not necessarily disabilities. Some differences can be real strengths. Who are Neurodivergent? The neurodiverse population includes people with specific diagnoses that are considered developmental disorders (as opposed to intellectual disabilities or mental illnesses). These include but are not limited to: Autism : A developmental disorder that includes differences in social communication skills, fine and gross motor skills, speech, and more Attention deficit hyperactivity disorder ( ADHD ): A neurodevelopmental disorder that includes features of inattention, hyperactivity, and impulsivity Tourette's syndrome : A tic disorder that starts in childhood ...

Ozobots - Educational bots

Image
Ozobots - Educational  bots Ozobot is a small, smart robot designed to introduce students to coding and robotics in a fun, hands-on way,  In its basic form, the Ozobot uses optic sensors to follow a drawn black line. The addition of color codes allows the robot to change direction or speed and allows students to create cool moves like a backwalk or tornado. Nader Hamda sets out to make small robots with a big mission. His 10-year-old daughter names the project Ozobot. After two years of testing and prototyping, Bit—the original Ozobot—is unveiled at CES in Las Vegas, Aug 2014 . Key Features and Functionality: Programmable : Ozobots can be programmed through color codes drawn on paper or via the OzoBlockly platform, allowing users to control its movements and actions.  Screen-Free Coding: The color code method is a screen-free way to learn coding, making it accessible for young learners.  Interactive Learning: Ozobots encourage hands-on learning and problem-solving, ...
