Find out Scholars Astronomers at the Massachusetts Institute of Technology and other astronomical research centers have detected a strange, steady radio signal from a distant galaxy flashing with surprising regularity. The signal is classified as a fast radio burst (FRB), a very strong burst of radio waves of unknown astrophysical origin, typically lasting a few milliseconds.

However, this new signal lasts up to three seconds, a thousand times longer than the average FRB, and is one of the longest-lasting signals ever. In this window, the team detected bursts of radio waves with a distinct periodic pattern every 0.2 seconds, similar to a heartbeat, according to their findings. study Published July 13 in the journal Nature.

Since the discovery of the first fast radio burst in 2007, hundreds of similar radio flashes have been observed across the universe, most recently by the Canadian Hydrogen Intensity Mapping Experiment, or CHIME, and most recently by radio telescopes measuring interferometry in the Four Large Parabolic Reflectors. CHIME continuously monitors the sky as Earth rotates, and is designed to capture radio waves emitted by hydrogen in the early stages of the universe’s life. The telescope is sensitive to fast radio bursts, and since it began observing the sky in 2018, it has detected Telescope Hundreds of fast radio bursts from different parts of the sky.

Most fast radio bursts observed so far are one-off, that is, ultra-bright bursts of radio waves that last a few milliseconds before flashing.

Researchers have finally discovered the first-ever fast radio burst that emits a regular pattern of radio waves, so it’s not a flash that fades away forever. This signal consists of four consecutive four-day random bursts, then repeated every 16 days. This 16-day cycle indicates the operation of the cycle system, although the actual radio burst signal was more random than the cycle.

The researchers have named the signal observed in the study FRB 20191221A, and it is the longest-lived FRB with the clearest periodic pattern detected to date, as these bursts usually disappear and are not regular.

The source of the signal is in a galaxy billions of light years away from Earth. What exactly would this evidence be? Neutron stars, two types of neutron stars with more dense and faster-spinning cores than giant stars, remain a mystery, although astronomers suspect that the signal may be emitted by a radio pulsar or magnetar.

Daniel Michael, a postdoctoral researcher at MIT’s Kavli Institute for Astrophysics and Space Research and lead author of the study, explains that periodic signals like this only come from a limited number of astronomical events. Examples we know in our galaxy are radio and magnetic pulsars, which spin and emit a beacon.

In a statement to Al-Araby Al-Jadeed, Michael says he believes the new signal could be a magnetar or a pulsar. The author hopes to find more periodic signals from this source, which can then be used as an astrophysical clock. The frequency of the pulses and how they change as the source moves away from Earth is used to measure the expansion rate of the universe.

Analyzing the pattern of detected radio bursts, Michael and colleagues found similarities with emissions from radio and magnetic pulsars in our galaxy. Radio pulsars are neutron stars that emit beams of radio waves and pulsate as the star rotates, while magnets produce uniform emission due to their intense magnetic fields. “The main difference between the new signal and radio emission from pulsars and magnetospheres in the galaxy is that the detected burst appears a million times brighter,” says the author.

Exciting information about the planet Uranus… don’t miss it



Exciting information about the planet Uranus… don’t miss it

Follow _ Lama Nasr:

The planet Uranus is one of the outer planets in our solar system. Uranus is considered the seventh planet after the Sun, and the third gas planet in the Solar System after Jupiter and Saturn.

Here are some interesting facts about the planet Uranus:

1. Its location and size: The planet Uranus is located in the solar system and is the seventh planet after Saturn. Uranus is the third largest planet in the Solar System in terms of diameter and size, four times the diameter of Earth.

2. Its peculiar spin axis: Uranus has an unusual spin axis because it is strongly tilted at approximately 98 degrees, meaning it spins on its side. This means that Uranus’ north pole and south pole experience longer periods of darkness and longer periods of light during the year.

3. Its icy composition: Uranus is believed to consist mainly of hydrogen and helium gas, with an outer layer of clouds containing ammonia and methane. These icy gases are responsible for Uranus’ cool blue color.

4. Discovery of rings: The rings of Uranus were discovered by observation from Earth in 1977. These rings consist of small particles of dust and ice. Unlike Saturn’s rings, Uranus’ rings are faint and difficult to see.

5. Space exploration: Uranus has not been visited by any human space mission, but it was visited by the Voyager 2 probe in 1986. Voyager 2 provided many detailed images of the planet and transmitted useful data about its atmosphere and rings.

6. Natural satellites: Uranus has 27 known natural satellites. The most prominent of these moons is “Miranda”, which appears to have a surface full of valleys and mountains, which is unique.

Here are some interesting facts about the planet Uranus. It is a unique and interesting planet that has many unique characteristics in the solar system.

Traces of DNA found in 6-million-year-old sea turtle fossil by Reuters



Traces of DNA found in 6-million-year-old sea turtle fossil by Reuters

(Reuters) – Traces of DNA have been found in the fossilized remains of a six-million-year-old sea turtle that closely resembled the Kemp’s ridley and the Olive sea turtle, researchers said on Thursday.

This is one of the rare times when genetic material has been found in the fossils of these ancient vertebrates.

The researchers reported that some bone cells were preserved in a very precise manner in the fossil extracted from the ground in an area located on the coast of Panama facing the Caribbean Sea. Image is incomplete. While the turtle’s shell is almost complete, the rest of the skeleton is incomplete. Researchers added that the turtle may have reached a length of 30 centimeters in its lifetime.

Paleobiologist Edwin Cadena said that in some bone cells, the nuclei were preserved and interacted with the chemical solution, allowing researchers to observe the presence of DNA residue. Activities. Cadena is one of the lead authors of the study published in Science (Journal of Vertical Paleontology).

Cadena added, “I would like to point out that we did not extract DNA, but only detected traces of DNA in the embryos.” Cadena is a researcher at the University of Rosario, Bogotá, and at the Smithsonian Tropical Research Institute.

— An ancient genus of sea turtles

Catena said two fossils of vertebrates older than this turtle have traces of the same DNA: Tyrannosaurus, which lived 66 million years ago, and Brachyliposaurus, which lived 78 million years ago. Cadena said traces of DNA have also been found in insects dating back tens of thousands of years.

The fossil represents the oldest known species of sea turtle and helps shed light on the species’ incompletely understood evolutionary history, the researchers said. Due to the incompleteness of the remains, Cadena said they were unable to biologically determine the turtle’s species.

“Every fossil and every fossil site has certain conditions that, in some cases, favor the preservation of remnants of the original biomolecules, such as proteins and DNA,” Catena said.

He added, “In the future, more studies of this species will sometimes be able to sequence very small pieces of DNA and infer things about their relatives in the same species, or add that information to a broader study of molecular evolution.”
