Hubble Captures Majestic Photo of a Galaxy with an ‘Explosive Past’

A new image from the Hubble Space Telescope shows a spiral galaxy about 150 million light-years away. But NASA says don’t be fooled: Its peaceful state masks a violent past.

Beautiful and peaceful now, but with a violent history
This “lazy winding spiral arm” image of galaxy NGC 976 was taken by the Hubble Space Telescope, courtesy of NASA and the European Space Agency (ESA). Despite its calm appearance, NGC 976 experienced one of the most violent astronomical phenomena: a supernova explosion, the space organization said.

“These catastrophically violent events occur at the end of a massive star’s life and can overtake entire galaxies in a short period of time,” NASA/ESA explained. “While supernovae mark the death of massive stars, they It also leads to the production of heavy elements, which are incorporated into future generations of stars and planets.”

Supernovae also help astronomers measure the distances of distant galaxies, as the energy released into space by certain types of supernova explosions is described as “remarkably uniform,” allowing them to estimate their distance from Earth based on the brightness of the light when it finally arrives.

In this latest image taken with Hubble’s Wide Field Camera 3, a series of observations from Hubble’s “nearby” galaxies (in quotation marks because they are still very far away from us, but very much in the grand scheme of the universe) close). Supernovae and “pulsating” stars called Cepheids.

“Both Cepheids and supernovae are used to measure astronomical distances, and galaxies containing both types of objects provide useful natural laboratories in which to calibrate the two methods against each other,” NASA explained.

Patterns of behaviour that emerge after trauma

Patterns of behaviour that emerge after trauma

Trauma is a deeply distressing or disturbing experience that can leave a lasting impact on a person’s mental and emotional health. It can result from a range of events, such as natural disasters, accidents, physical or emotional abuse, or military combat. Trauma can have a significant effect on a person’s behavior and can manifest in various ways. Here are some patterns of behavior that often emerge after trauma:

  1. Hyperarousal: After experiencing trauma, a person may feel constantly on edge, with heightened levels of anxiety and tension. This can manifest as irritability, restlessness, and difficulty sleeping.
  2. Avoidance: Trauma can also cause a person to avoid situations, people, or places that remind them of the traumatic experience. This can lead to social withdrawal, isolation, and a loss of interest in previously enjoyable activities.
  3. Emotional numbness: Trauma can cause a person to feel emotionally disconnected or numb, making it difficult for them to experience positive emotions such as joy or love.
  4. Hypervigilance: A person who has experienced trauma may be hyper-aware of their surroundings and perceive threats where none exist. This can lead to an increased sense of danger, which can trigger anxiety or panic attacks.
  5. Flashbacks: Trauma can cause a person to experience vivid and intrusive memories of the traumatic event. These flashbacks can be triggered by a range of stimuli, such as sights, sounds, or smells.
  6. Guilt and shame: Trauma can cause a person to experience feelings of guilt, shame, and self-blame. They may feel responsible for what happened to them, even when it was beyond their control.
  7. Substance abuse: Trauma can lead to the use of drugs or alcohol as a way of coping with difficult emotions. This can quickly become a self-destructive pattern of behavior that exacerbates the trauma.

It’s important to note that not everyone who experiences trauma will display all of these behaviors, and that each person’s response to trauma is unique. However, recognizing these patterns of behavior can help individuals and their loved ones identify when trauma may be a contributing factor to mental and emotional health challenges. Seeking professional support, such as therapy or counseling, can help individuals process their trauma and learn healthy coping mechanisms to manage their behavior.
