NASA has released the first scientific images from the James Webb Space Telescope.
NASA has released the first scientific images from the James Webb Space Telescope.
It shows “the oldest documented light in the history of the universe, from over 13 billion years ago” said US President Joe Biden when he released the first image.
The Webb telescope is able to penetrate clouds of dust and can capture images of newborn stars. And these images are “the deepest and sharpest infrared” images of the distant universe to date, according to NASA Administrator Bill Nelson.
“Webb is just the start of what we can accomplish in the future when we work together for the benefit of humanity,” Nelson added.

Should we worry about monkeypox?
Monkeypox cases continue to rise around the world, and the World Health Organization (WHO) plans to consider whether it should be a public health emergency of international concern.
WHO’s Emergency Committee previously determined in June that the outbreak did not meet the criteria to be classified as “an extraordinary event that constitutes a public health risk to other states through the international spread of disease.”
The virus continues to spread, however, and CNN reports that WHO Director-general Tedros Adhanom Ghebreyesus wants the committe to reassess based on the latest data.
Monkeypox is a viral disease that is endemic in central and western Africa. The disease, however, has spread to many regions of the world.

Astrophysicist Neil deGrasse Tyson reacts to Elon Musk’s tweets on Mars colonization.
Five days ago, Musk posted through Twitter threads that the “population of Mars is still zero people,” and that “Humanity will reach Mars in your lifetime. Without a common goal, humanity will fight itself. Moon brought us together in ‘69, Mars can do that in the future.”
In CNN’s interview, Tyson said that we do have human presence on Mars through “generations of rover[s],” which are in communication with people on Earth.
Tyson also emphasized aside from his argument that people would not want to live on Mars, sending people to the red planet is more expensive than sending robots because people would need to eat and would want to come back to Earth.
Tyson also said that it would be difficult to control the forces of Mars since “we’re still victims of our own forces of nature on Earth” like hurricanes, tornadoes, and earthquakes.

The fin whales are back!
Fin whales, endangered because of industrial whaling in the 20th century, returned in large groups to their ancestral feeding grounds at the Antarctic Peninsula, study finds.
As stated in the Scientific Reports article, their return as top predators could restore certain ecosystem functions and stability lost during the 20th century.
It also raises “hope that fin whales are on their way to pre-exploitation numbers,” the researchers wrote. This is also good indication that the ban on commercial whaling almost 50 years ago works.

Dogs traced back to two wolf populations

How did dogs become pets?
A study by the Francis Crick Institute shows that dogs “can be traced to at least two populations of ancient wolves,” revealed by Ice Age wolf DNA. This is a step closer to solving one of the biggest mysteries—how did dogs become man’s best friend.
