Earthlings are set to witness a rare stellar phenomenon that happens once in approximately every 80 years. It is expected that a nova will take place soon in the coming months. Nova is referred to as an explosion in a binary star system.The star system in question is called T Coronae Borealis , or " T CrB ". It is composed of two stars that belong to two distinct categories: a white dwarf, and a red star. The upcoming eruption in T Coronae Borealis is likely to be visible to the naked eye for a brief period. The star system has been under the watch of astronomers for quite some time now.T Coronae Borealis, which is a part of the Northern Crown constellation, is located nearly 3,000 lightyears away from Earth. The periodic nova in the star system results from the over-accumulation of gases around the white dwarf. The impact of thermonuclear explosion only impacts the surface of the Earth-sized remnant.The gases that build up around the white dwarf over time are emitted by the red giant. The process takes several thousand years to complete a full cycle in most cases. However, in the case of T CrB, it does so in just 80 years, making it a lifetime event for most people.Past novae in the binary system are known to have occurred in 1787, 1866, and 1946. Prior to that, an outburst was likely recorded in 1217. The latest explosion in T CrB was earlier expected to take place in late 2024. However, that obviously did not happen. It is hard to predict when a Nova will exactly occur. In recent years, astronomers started observing T CrB when it appeared to lose its brightness.As per NASA , the anticipated nova eruption greatly interests astronomers as such events are relatively rare in Earth's vicinity. The outburst's proximity from Earth will enable scientists to observe the event in unusual detail. An average nova can be around 200,000 times brighter, as compared to the Sun. The brightest nova can be 10 times brighter than that, as per NASA.The nova explosion in T CrB repeats itself every 80 years or so.The last stellar explosion in T CrB was documented in 1946.

Elon Musk has a SpaceX ‘challenge' for NASA's entire budget for 2026

Elon Musk has issued a financial "challenge" to NASA, stating that SpaceX 's commercial revenue will exceed the entire budget of the government space agency in 2026. The tech billionaire, who is also the CEO of SpaceX, took to the social media platform X (earlier Twitter) to predict that the rocket maker is projected to record nearly $15.5 billion in revenue this year. This figure highlights SpaceX's increasing presence in the commercial space sector . In his X post, Musk specifically noted that SpaceX's commercial revenue from space operations in 2026 will surpass NASA 's projected budget of roughly $1.1 billion for that same year. In the X post, Musk wrote: 'Perhaps an interesting milestone: @SpaceX commercial revenue from space will exceed the entire budget of @NASA next revenue this year will be ~$15.5B, of which NASA is ~$1.1B.' How Elon Musk's SpaceX may be able to achieve this feat by Taboola by Taboola Sponsored Links Sponsored Links Promoted Links Promoted Links You May Like Giao dịch CFD với công nghệ và tốc độ tốt hơn IC Markets Đăng ký Undo According to a report by the news agency Reuters, while NASA continues to fund deep space exploration and scientific missions, SpaceX seems to have capitalised on rising demand for affordable launch services and satellite-based communications to drive revenue growth. SpaceX is also developing its 400-foot (122-meter) Starship rocket, which Elon Musk has said will be vital in enabling future human missions to Mars. SpaceX's reusable Falcon 9 and Falcon Heavy rockets have significantly lowered launch costs, helping the company capture a dominant share of the global launch market. In 2024, SpaceX completed 134 Falcon launches — a record-breaking achievement that made it the most active launch operator worldwide. As per the Reuters report, the company aims to surpass this milestone with 170 launches by year-end to keep up with increasing satellite deployment demand. The report also notes that much of SpaceX's revenue stems from its Starlink satellite internet service. Musk has said Starlink will go public, though no timeline has been confirmed. In November 2023, Musk announced that Starlink had reached breakeven cash flow. Thousands of Starlink satellites have already been deployed to provide global broadband coverage. Additionally, as per Reuters, SpaceX and two other partners have become leading contenders to secure a key role in the US 'Golden Dome' missile defence initiative, a project backed by President Donald Trump.

James Webb Telescope clicks pictures of a galaxy with 800 billion Suns

James Webb Telescope clicks picture of a galaxy with 800 billion Suns 04 Jun, 2025 Credit: Nasa NASA's Webb Telescope captured a near-infrared image of the Sombrero galaxy, highlighting its bright central bulge while revealing less of the dust disk due to infrared light's ability to pass through dust. Observing the galaxy in visible (Hubble), near-IR, and mid-IR (Webb) helps astronomers study how stars, dust, and gas interact and evolve over time. The mid-infrared image shows the galaxy's dust glowing, while in near-infrared, stars shine through more clearly, making the dust less pronounced. Located 30 million light-years away, the Sombrero galaxy is seen nearly edge-on and has a mass equivalent to about 800 billion Suns. Variations in the chemical makeup of its 2,000+ globular clusters suggest the galaxy may have merged with another galaxy in the past. A noticeable warp in the inner disk, visible due to our slightly tilted viewing angle, supports the idea of a past galactic merger. Webb's powerful resolution reveals red giant stars and a colorful array of distant background galaxies, offering more clues about stellar evolution and cosmic structure.

After 50 Successful Years, The European Space Agency Has Some Big Challenges Ahead

This year marks the 50th anniversary of the founding of the European Space Agency (Esa). It has launched spectacularly successful missions, but is different to other space agencies which generally represent one country. Esa is funded by 23 member states and also has cooperation agreements with nations such as Canada. Esa operates cutting edge spacecraft designed to monitor the Earth, as well as space telescopes that study the distant cosmos. It has launched robotic spacecraft to other planets and to objects such as comets. It is also involved in human spaceflight – training European astronauts to work on the International Space Station (ISS). These are hugely successful achievements. But the agency now faces challenges as competition heats up among newer space powers such as China and India. The history of Esa can be traced to events immediately after the second world war, when many European scientists moved to either the US or to the Soviet Union. Many of them realised that projects supported only by a single nation could not compete with those supported by the two big geopolitical players at the time. This motivated the physicists Pierre Auger, from France, and Edoardo Amaldi, from Italy, to propose a European organisation that would carry out space research and would be 'purely scientific'. In 1962, two agencies were created. One of these, the European Launch Development Organisation (ELDO), would concentrate on developing a rocket. The other, the European Space Research Organisation (ESRO), would focus on developing robotic spacecraft. Both were joined together in 1975 to form the European Space Agency. The push to build a European rocket would eventually yield the Ariane launcher, which is operated by the French company Arianespace. The first satellite to be launched under the banner of the newly formed European Space Agency was Cos-B. This spacecraft was designed to monitor a high energy form of radiation called gamma rays, being emitted from objects in space. In 1978, Esa cooperated with Nasa and the UK on the International Ultraviolet Explorer mission. This space telescope was designed to observe the cosmos in ultraviolet light, something that cannot be done from Earth. The agency would later collaborate with Nasa and the Canadian Space Agency on one of the most successful space telescopes of all time: Hubble. Launched in 1990, the Hubble Space Telescope helped confirm the expansion rate of the universe and showed that black holes are at the cores of almost all galaxies. Hubble's stunning images also changed the way that many people saw the universe. Esa funded one of the original instruments on the space telescope, the Faint Object Camera, and provided the first two solar arrays. The space agency is also a partner on the revolutionary James Webb Telescope, which launched in 2021. Esa contributed two of the telescope's instruments: the Near-Infrared Spectrograph (NirSpec) and the Mid-Infrared Instrument (Miri). Solar System Missions Esa has also launched pioneering missions to other planets and objects in our solar system. The first of these was the Giotto comet explorer. This robotic spacecraft flew past Halley's comet in 1986 and was successfully woken up in 1992 to study a comet called Grigg-Skejllerup. A second successful cometary mission followed when the Rosetta spacecraft entered orbit around Comet 67P/Churyumov-Gerasimenko in 2014. Rosetta despatched a lander called Philae to touch down on the comet's surface. Rosetta has been my favourite of all Esa achievements, simply due to the pure audacity of attempting to land on an object whose shape and composition was until then only sparsely known. In order to 'land' on an object with low gravity, Philae was to have deployed harpoons that would attach the lander to the surface. These systems did not work, but the overall mission was a success, leading to high levels of engagement from the public. Besides comets, Esa launched one of the most successful missions to the red planet: Mars Express. The spacecraft entered orbit around Mars in 2003 and has played a key role in enhancing understanding of our planetary neighbour. It is expected to continue working until at least 2034. Mars Express also carried the ill-fated British Beagle 2 spacecraft to Mars. This was supposed to land in 2003, but contact was never established with the probe, which is presumed to have been damaged while touching down. In 2005, Esa's Huygens spacecraft landed on Titan, Saturn's largest moon. This was the furthest from Earth that a spacecraft has ever landed. These are all outward facing missions, but Esa has also had major success with projects to study what's going on here on Earth. These include the Envisat satellite, which operated from 2002-2012, and the Sentinel series of spacecraft, which have operated from 2014 to the present. These have helped map agriculture and forests, understand the Earth's climate, track ice, and monitor atmospheric ozone. In addition, the Galileo navigation satellites are providing a high precision alternative to GPS. Esa is also a major player in human spaceflight, having been a partner in the International Space Station project since 1993. It has built sections of the ISS, including the Columbus laboratory, launched in 2008, and the Cupola viewing window, which gives astronauts panoramic views of Earth. The agency's astronauts regularly spend time on the ISS as crew and could even fly to the Moon under Nasa's Artemis programme. Since the 1990s, Esa has frequently collaborated with Nasa – often very successfully. However, this relationship has also faced challenges. In the wake of the financial crisis, for example, Nasa cancelled its participation in several collaborative missions with Esa. Under a proposed Nasa budget this year, the US space agency may again cancel its involvement with the joint Nasa-Esa Mars Sample Return mission. Esa's Future Times have changed in the space industry since Esa's founding 50 years ago. Major countries such as China, India and Japan all have their own space programmes. Esa faces considerable financial pressures to compete with them. Nevertheless, Esa is working on strengthening its space exploration and launch capabilities through the use of a commercial space port in Norway. It has also put together a long-term strategy for 2040. This document highlights important areas where Esa can play a major role, including protecting Earth and its climate, continued missions to explore space and also efforts to boost European growth and competitiveness. All this should strengthen and secure the agency for the future. Through a mixture of developing its own missions and collaborating with other agencies and commercial partners on others, Esa should be a major player in space exploration for decades to come.
