Tesla CEO Elon Musk has deployed his satellite-based Starlink service in Iran amid widespread protests in the country following which authorities had restricted internet access.

This Iranian government had cut off internet access for many of its citizens on Wednesday amid widespread protests over the death of a 22-year-old woman, Mahsa Amini, in police custody, according to reports.

On Friday, SpaceX founder Elon Musk had indicated that he will make Starlink available in Iran.

US State Secretary Antony Blinken earlier announced on Twitter about advancing internet freedom and the free flow of information for the Iranian people by issuing a General License to provide them greater access to digital communications to counter, what he claimed, was the Iranian government’s censorship.

Replying to Blinken’s tweet, Musk wrote, “Activating Starlink.”

Protestors have been demanding basic rights of freedom and holding demonstrations against the mandatory dress codes including the compulsory wearing of the Hijab.

The protests in Iran erupted last weekend after Mahsa Amini died following her detainment by Iran’s morality police. She died a few days after falling into a coma while being detained on an accusation of violating a law related to hijabs.

It is worth noting that earlier this week, lawmakers from New York and New Jersey had urged the US Treasury Department to grant approval if SpaceX sought licensing permission to make internet service available in Iran.

Lawmakers, led by Claudia Tenney of New York and Tom Malinowski of New Jersey, reportedly made the appeal to the Treasury Department, Fox News had reported. The letter came after Musk tweeted Monday that SpaceX would seek exemptions from sanctions on the country.

SpaceX has deployed Starlink in emergency situations in past, such as in Ukraine after Russia invaded and in the South Pacific islands of Tonga after a volcanic eruption.

NASA Reveals a Fracture in Huge Cosmic Bone: Everything You Need to Know

X-ray is a very common method that almost every individual is well aware of. However, ever wondered what an X-ray of the Milky Way would look like? Or is that even possible? Well, yes, it is. Recently, NASA’s Chandra X-Ray Observatory has carried out an image of a recent scan, which revealed a fractured bone. As specified in Space.com, the bone-like structure, which was witnessed in the X-ray image, was derived from the radio data obtained by the MeerKAT Radio Array in South Africa and the National Science Foundation’s Very Large Array in New Mexico.

About the Cause of Fracture

According to the data obtained from Chandra’s X-ray, the fracture, also known as the galactic center filament, was caused by the impact from a pulsar. A pulsar is a spinning neutron star that emits radiation constantly at regular intervals. Revealed in Space.com, the scientists are highly skeptical about the speed of the pulsar, during slamming, would have been between one to two million miles per hour.

What is a Galactic Center Filament

Milky Way, undoubtedly, does not consist of bone. However, what looks like a real bone is a Galactic Center Filament, which is an amalgamation of structures crafted by the radio waves interwoven with the magnetic fields, right at the center of the Milky Way.

What did scientists discover?

As conveyed to Space.com, this is one of the brightest and longest galactic center filaments that have been detected so far. The distances of these filaments are 26,000 light-years and 230 light-years long. The bone has been named as G359.13142-0.20005.

The Scientist’s Verdict

Narrated to Space.com, the scientists suggest that the collision with the neutron stars would have dismantled the filament’s magnetic field, which further resulted in the fracture. The scientists are hopeful that the fracture will heal itself.

NASA Telescopes Reveal Hidden Properties of X-Ray Pulsar RX J0032.9-7348

NASA Telescopes Reveal Hidden Properties of X-Ray Pulsar RX J0032.9-7348

Pulsars are neutron stars rotating rapidly, emitting electromagnetic radiation in various wavelengths, including radio waves, optical, X-ray, and gamma-ray. Identified as a X ray transient source in the Small Magellanic Cloud (SMC) about 30 years ago, RX J0032.9-7348 has been classified as an X-ray Pulsar after detecting X-ray pulsations with a period of approximately 7.02 seconds after experiencing an X-ray brightening in October 2024.To take a closer look at it, astronomers have incorporated two NASA X-ray telescope, NICER and NuSTAR.

Discovery and Observational Campaign

According to Handbook of X-ray and Gamma ray Astrophysics, Accretion-powered X-ray pulsars (XRPs) are neutron stars within binary systems that emit X-rays in regular pulses, powered by the accretion of matter from a companion star. However, although RX J0032.9-7348 has been known for decades, very little is known regarding its properties and its optical counterpart has not been identified. Therefore, a team of astronomers led by Birendra Chhotaray of the Physical Research Laboratory (PRL) in Ahmedabad, India, decided to take a closer look at this pulsar with NuSTAR and NICER.
Dr Chhotaray and his team were able to verify the X-ray pulsation period of RX J0032.9-7348 through their observations and they also discovered that this pulsar has a double-peak pulse profile throughout a wide energy range, with small changes in the form of energy dependence.

Findings

Results of the observational campaign, published on the arXiv preprint server, gives insight of the spin dynamics and luminosity of this pulsar. The accretion processes during the X-ray brightening phase increases its angular momentum. It results into a spin-up of approximately -0.00033 seconds per day.
The luminosity of the pulsar varied from 8.2 undecillion to 37 undecillion erg/s during the monitoring campaign. The researchers report that no evidence of iron emission line or cyclotron resonance scattering features was found in the energy spectrum of this source.

Soviet Venus Probe Kosmos 482 Set to Re-Enter Earth After 53 Years in Single Piece

Kosmos 482, under the USSR Venera program, was launched into space in 1972 to land on the second planet. However, the rocket malfunctioned and in Earth’s orbit, and it’s still revolving there ever since. Its rugged design lets it stay there and tolerate the atmosphere of Venus. This durability implies that it could survive reentry into Earth and remain intact with no impact. It is supposed to land either on 9 or 10 May without actually breaking anything up. The Aerospace Corporation is tracking it through the radar data provided by the U.S Space network surveillance.

When and Where Might It Land?

As per the current forecasts, ESA reports that the lander will re-enter the Earth’s atmosphere on Saturday, May 10, 12:37 PM EST, with an error margin of ±20.6 hours. Due to an orbital inclination of 52 degrees, it is possible that it could land between the vast regions including Australia, South America and Africa, and in water covering these areas. On the map, it is between 52 degrees North and 52 degrees south. It may fall into the ocean, as 70% of the Earth is water.

What Happens If It Survives Reentry?

If Kosmos 482 reaches the Earth in one piece, the speed would be 150-250 km per hour. The structure would be the same, that is, around 1 meter in diameter and 495 kgs in weight. The scientists predict that the parachute system must have no longer been there after 53 years in space.

Exact Timing Become Challenging

Solar activities, such as storms, are adding complexity to the radar data sometimes which in turn is impacting the reentry timings. Langbroek says, The Sun does whatever it wants to do, making it difficult to analyse the exact hours until the last moment.

Risk to the Public Is Low

Scientists say that the risk to humans is minimal, with a 0.4% chance of death or even injury. It will come down as a single object, with no debris risk. However, if anyone happens to encounter is should stay away and not touch it, simply report to the local authorities.
