Hubble discovers unusual wrinkles in the rate of expansion of the universe
Over the past 30 years, the Space Observatory has helped scientists discover and refine this rate of acceleration, as well as reveal puzzling problems that only new physics can solve.
Hubble has detected more than 40 galaxies containing pulsars as well as exploding stars called supernovae to measure large cosmic distances. These two phenomena help astronomers define astronomical distances as miles markers that indicate expansion rates.
In their quest to understand how rapidly our universe is expanding, astronomers made an unexpected discovery back in 1998: “dark energy.” This phenomenon acts as a mysterious driving force, accelerating the rate of expansion.
And there is another event: the inexplicable difference between the rate of expansion of the local universe and the rate of expansion of the distant universe immediately after the Big Bang.
Scientists do not understand the paradox, but admit that it is strange and may require new physics.
“You get the most accurate measure of the expansion rate of the universe with the gold standard for telescopes and space tilt markers,” said Adam Reese, Nobel Prize winner at the Space Telescope Science Institute and professor emeritus at Johns Hopkins University in Baltimore. in the current situation.
“That’s what the Hubble Space Telescope was built for, using the best technology we know. This is probably the Hubble magnum, because it will take another 30 years of Hubble’s life to double the size of this sample.”
decades of observation
The telescope is named after pioneering astronomer Edwin Hubble, who discovered in the 1920s that distant clouds in the universe are actually galaxies. (died 1953).
Hubble built on astronomer Henrietta Swan-Levitt’s 1912 work to detect periods of brightness in pulsars called variable Cepheids. Cepheids act as cosmic tilt markers because they periodically light up and dim in our galaxy and beyond.
Hubble’s work led to the discovery that our galaxy was one of many that forever changed our perspective and our place in the universe. The astronomer continued his work and found that distant galaxies appear to be moving rapidly, suggesting that we live in an expanding universe that began with the Big Bang.
Reiss continues to lead SHOES, short for Supernova, H0, for the equation of state for dark energy, a scientific collaboration that explores the expansion rate of the universe. His team publishes a paper in The Astrophysical Journal that provides the latest information on the Hubble constant since the expansion rate is known.
unresolved contradiction
Measuring distant objects has created a “cosmic distance ladder” that could help scientists better estimate the age of the universe and understand its foundations.
Several groups of astronomers using the Hubble telescope have come up with a Hubble constant of 73 plus or minus 1 kilometer per second per megaparsec. (One megaparsec is equal to one million parsecs, or 3.26 million light years.)
“The Hubble constant is a special number,” he said. “It can be used to thread a needle from the past into the present to test a comprehensive understanding of our universe. It required a huge amount of detailed work.” This was stated by a cosmologist from the Catalan Institute for Research and Advanced Studies and the Institute of Cosmology of the University of Barcelona Lecia Verdi.
But the actual rate of expansion expected from the universe is slower than the rate observed by the Hubble telescope, according to astronomers using the Standard Cosmological Model of the Universe (a theory that refers to the components of the Big Bang) and measurements made by the European Space Agency. Planck. work from 2009 to 2013.
The Planck Observatory, another space-based observatory, was used to measure the cosmic microwave background, or residual radiation from the Big Bang 13.8 billion years ago.
Planck’s scientists achieved the Hubble constant of 67.5 plus or minus 0.5 kilometers per second per megaparsec.
This presents an exciting challenge for cosmologists who were once determined to measure the Hubble constant and are now wondering what additional physical data could help them unravel the new mystery of the universe.
“I don’t really care about the specific value of the scale, but I like to use it to understand the universe,” Reese said.

NASA Lander InSight He has delivered what may be his last message from Mars as he embarks on a historic mission to uncover the secrets of the Red Planet’s interior.
In November, the space agency warned that the probe could be running out of time as dust continued to condense and stifle InSight’s power.
“Spacecraft power generation continues to decline as windblown dust accumulates on solar panels,” NASA said in a statement. Update November 2. “The end is expected to come in the coming weeks.”
message shared NASA The InSight Twitter account tweeted on Monday: “My power is very low so this might be the last photo I can upload. Don’t worry about me: my time here has been productive and uneventful. If I can keep talking to my mission team, I will—but I will.” Subscribe here soon. Thank you for staying with me.”

A geologist robot armed with a hammer and a seismograph first reached the barren expanse of Elysium Planitia in November 2018.
Since then, she has carried out geological excavations, taking the first measurements of earthquakes with a high-tech seismometer placed right on the surface of Mars.
Last month, the solar-powered car released an update to remind us of its time in space.
“I was lucky to live on two planets. Four years ago I made it safely to the second one, much to the joy of my family at first. Thanks to my team for taking me on this journey of discovery. I hope I can be proud of you.”
According to the published mission, Insight has measured more than 1,300 seismic events since it was published, and more than 50 of them had signals clear enough for the team to extract information about their location on Mars. Results.
The probe’s data also provided detailed information about Mars’ interior, liquid core, surprisingly variable remnants beneath the surface of an extinct magnetic field, climate and seismic activity.
old for Its launch in 2018NASA Chief Scientist Jim Green said the mission was “fundamental to understanding the origins of our solar system and how it became what it is today.”
NASA will not declare the mission complete until Insight confirms the arrival of two spacecraft orbiting Mars that are relaying their information back to Earth.
In 2018, the veteran rover announced the capabilities end of his 15 year stay Sending an incomplete photo of the Valley of Perseverance.
A severe dust storm darkened the sky around the solar-powered rover, shattering the sun and leaving behind a dark image with white spots due to camera noise. The transmission is interrupted before the complete image can be transmitted.

Being very close companies, OPPO and OnePlus have decided to create a new partnership, with the latter being a pioneer in the market. It has become the representative of the best smartphones in the group, and this will be seen very soon.
Proving this, OnePlus has announced that it will have news soon. The following brand assets will be announced on February 7, 2023. We are talking about OnePlus 11 5G and Buds Pro 2.
In recent years, OnePlus has been showcasing new hardware in an attempt to find a new place in the market. The brand has not always seen its full potential, betting on mid-range or entry-level smartphones.
The situation is changing, and the novelty will go on sale in early 2023, February 7. It is on this day that the new OnePlus 11 5G will be presented with all the expected news. We definitely have the new Qualcomm Snapdragon 8 Gen 2 SoC here. There's still 16GB of storage left and 256GB of onboard storage.
It is expected that he will receive a 6.7-inch OLED display with a resolution of 1440p and a frequency of 120 Hz. In the field of photography, we will have an important change: a 50 MP main camera, a 48 MP ultra wide-angle camera and a 32 MP telephoto lens with 2x zoom. For selfies and video calls, you'll have a 16-megapixel camera.
The photography partnership with Hasselblad will continue with OnePlus for fine-tuning and some additions. This alliance has brought important results for the best smartphones of the brand, guaranteeing the best photos in any situation.
In addition to the new OnePlus 11 5G, another brand new feature is also expected to arrive at the event. We're talking about the Buds Pro 2, which are solidifying an audio commitment that's becoming more of a reality. The brand promises "rich stereo quality sound with crystal clear clarity".
