<p style="margin-right:0in"><span style="font-size:11pt"><span style="font-family:Calibri,sans-serif">Using the <strong>European Space Organisation’s</strong> (ESO) <strong>Very Large Telescope</strong> (VLT), astronomers have noticed the unprecedented dimming of Betelgeuse, a red supergiant star in the constellation Orion.</span></span></p>
<p style="margin-right:0in"> </p>
<p style="margin-right:0in"><span style="font-size:11pt"><span style="font-family:Calibri,sans-serif"><strong>Background</strong></span></span></p>
<p style="margin-right:0in"><span style="font-size:11pt"><span style="font-family:Calibri,sans-serif">A <strong>red</strong> <strong>giant</strong> is a luminous giant star of low or intermediate mass in a late phase of stellar evolution. The outer atmosphere is inflated and tenuous, making the radius large and the surface temperature around 5,000 K or lower.</span></span></p>
<p style="margin-right:0in"> </p>
<p style="margin-right:0in"><span style="font-size:11pt"><span style="font-family:Calibri,sans-serif"><strong>Details</strong></span></span></p>
<ul>
<li>
<p><span style="font-size:11pt"><span style="font-family:Calibri,sans-serif">What has intrigued some astronomers is the fact that along with the dimming, the star’s shape has been changing as well. Instead of appearing round, the star now appears to be “squashed into an ova”.</span></span></p>
</li>
<li>
<p><span style="font-size:11pt"><span style="font-family:Calibri,sans-serif"><strong>Betelgeuse</strong> was born as a supermassive star millions of years ago and has been dramatically and mysteriously dimming for the last six months.</span></span></p>
</li>
<li>
<p><span style="font-size:11pt"><span style="font-family:Calibri,sans-serif">The report suggests that while Betelgeuse’s behaviour is out of the ordinary, it doesn’t mean that an eruption is imminent since astronomers predict the star to blast sometime (supernova explosion) in the next 100,000 years or so.</span></span></p>
</li>
<li>
<p><span style="font-size:11pt"><span style="font-family:Calibri,sans-serif">Astronomers do not think that Betelgeuse is dimming because it is going to explode. They have other hypotheses that may explain the reasons for Betelgeuse’s change in shape and dimming.</span></span></p>
</li>
<li>
<p><span style="font-size:11pt"><span style="font-family:Calibri,sans-serif">The two scenarios are a cooling of the surface due to exceptional stellar activity or dust ejection towards us.</span></span></p>
</li>
</ul>
<p style="margin-right:0in"><span style="font-size:11pt"><span style="font-family:Calibri,sans-serif"><strong>Supernova</strong> </span></span></p>
<ul>
<li>
<p><span style="font-size:11pt"><span style="font-family:Calibri,sans-serif">A supernova is a powerful and luminous stellar explosion. This transient astronomical event occurs during the last evolutionary stages of a massive star or when a white dwarf is triggered into runaway nuclear fusion. </span></span></p>
</li>
<li>
<p><span style="font-size:11pt"><span style="font-family:Calibri,sans-serif">The original object, called the progenitor, either collapses to a neutron star or black hole, or it is completely destroyed. The peak optical luminosity of a supernova can be comparable to that of an entire galaxy, before fading over several weeks or months.</span></span></p>
</li>
<li>
<p><span style="font-size:11pt"><span style="font-family:Calibri,sans-serif">Theoretical studies indicate that most supernovae are triggered by one of two basic mechanisms: the sudden re-ignition of nuclear fusion in a degenerate star; or the sudden gravitational collapse of a massive star's core.</span></span></p>

<p style="margin-right:0in"><span style="font-size:11pt"><span style="font-family:Calibri,sans-serif">A <strong>red</strong> <strong>giant</strong> is a luminous giant star of low or intermediate mass in a late phase of stellar evolution. The outer atmosphere is inflated and tenuous, making the radius large and the surface temperature around 5,000 K or lower.</span></span></p>

<ul>
<li>
<p><span style="font-size:11pt"><span style="font-family:Calibri,sans-serif">What has intrigued some astronomers is the fact that along with the dimming, the star’s shape has been changing as well. Instead of appearing round, the star now appears to be “squashed into an ova”.</span></span></p>
</li>
<li>
<p><span style="font-size:11pt"><span style="font-family:Calibri,sans-serif"><strong>Betelgeuse</strong> was born as a supermassive star millions of years ago and has been dramatically and mysteriously dimming for the last six months.</span></span></p>
</li>
<li>
<p><span style="font-size:11pt"><span style="font-family:Calibri,sans-serif">The report suggests that while Betelgeuse’s behaviour is out of the ordinary, it doesn’t mean that an eruption is imminent since astronomers predict the star to blast sometime (supernova explosion) in the next 100,000 years or so.</span></span></p>
</li>
<li>
<p><span style="font-size:11pt"><span style="font-family:Calibri,sans-serif">Astronomers do not think that Betelgeuse is dimming because it is going to explode. They have other hypotheses that may explain the reasons for Betelgeuse’s change in shape and dimming.</span></span></p>
</li>
<li>
<p><span style="font-size:11pt"><span style="font-family:Calibri,sans-serif">The two scenarios are a cooling of the surface due to exceptional stellar activity or dust ejection towards us.</span></span></p>
</li>
</ul>
<p style="margin-right:0in"><span style="font-size:11pt"><span style="font-family:Calibri,sans-serif"><strong>Supernova</strong> </span></span></p>
<ul>
<li>
<p><span style="font-size:11pt"><span style="font-family:Calibri,sans-serif">A supernova is a powerful and luminous stellar explosion. This transient astronomical event occurs during the last evolutionary stages of a massive star or when a white dwarf is triggered into runaway nuclear fusion. </span></span></p>
</li>
<li>
<p><span style="font-size:11pt"><span style="font-family:Calibri,sans-serif">The original object, called the progenitor, either collapses to a neutron star or black hole, or it is completely destroyed. The peak optical luminosity of a supernova can be comparable to that of an entire galaxy, before fading over several weeks or months.</span></span></p>
</li>
<li>
<p><span style="font-size:11pt"><span style="font-family:Calibri,sans-serif">Theoretical studies indicate that most supernovae are triggered by one of two basic mechanisms: the sudden re-ignition of nuclear fusion in a degenerate star; or the sudden gravitational collapse of a massive star's core.</span></span></p>
