NASA announces astronomical event visible to the naked eye: When and how to observe it?

The National Aeronautics and Space Administration (NASA) announced a unique event that can be seen from Earth, and without a telescope, next September.

HUILA DIARY, ASTRONOMY

The National Aeronautics and Space Administration (NASA) has announced an exceptional astronomical event that can be observed from Earth without a telescope next September. It is the ‘Blaze star’, scientifically known as the T CrB nova. This phenomenon occurs in a binary system composed of a white dwarf (a small star in the initial phase of its evolution) and a red giant (an evolved star of low and intermediate mass, like the Sun, which has a long life).

In non-scientific terms, the ‘Blaze’ phenomenon is a thermonuclear explosion that expels material into space, generating blinding and gigantic flashes. This happens because hydrogen from the red giant accumulates on the white dwarf, creating heat and pressure that trigger the event.

An unparalleled astronomical spectacle: This event will be visible without the aid of telescopes, thanks to its incredible brightness, reaching a magnitude of 2, comparable to the brightest stars in the night sky.

The particularity of the phenomenon

What makes this event unique, according to NASA’s Dr. Hounsell, is that it will be visible without the aid of telescopes. The thermonuclear explosion will be so bright that it can be seen as one of the stars in the night sky, reaching a magnitude of about 2.

The T CrB nova was first observed in Germany in 1217, and was last seen in 1946. Based on this pattern, astronomers predicted the next explosion would occur in 2024.

How to observe the Blaze star?

To observe the blaze star, experts recommend looking for the constellation Hercules and locating the Northern Crown, a horseshoe-shaped curve of stars, during the night, when it is most visible. Observers should identify the two brightest stars in the northern hemisphere (Arcturus and Vega) and then look between them to see the point of the explosion. This astronomical event will be visible throughout the month of September this year.

Recommendations for observing the event

1. Planning: Identify a location with clear skies and low light pollution to improve visibility of the event.

2. Date and Time: Although the phenomenon will be visible throughout the month of September, the best times will be during moonless nights, when the sky is darker.

3. Optional equipment: While a telescope is not required, the use of binoculars could enhance the experience, allowing you to see more details of the event.

4. Education: Take the opportunity to learn more about the phenomenon and share the event with friends and family, making the sighting an educational and social experience.
